+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier. All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads. This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies. See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * b = 2;
+ * memory_barrier();
+ * p = &b; q = p;
+ * read_barrier_depends();
+ * d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends(). However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * a = 2;
+ * memory_barrier();
+ * b = 3; y = b;
+ * read_barrier_depends();
+ * x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b". Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+ * in cases like this where there are no data dependencies.

+ * NOTES about DMA transfers:
+ *
+ * controller 1: channels 0-3, byte operations, ports 00-1F
+ * controller 2: channels 4-7, word operations, ports C0-DF
+ *
+ * - ALL registers are 8 bits only, regardless of transfer size
+ * - channel 4 is not used - cascades 1 into 2.
+ * - channels 0-3 are byte - addresses/counts are for physical bytes
+ * - channels 5-7 are word - addresses/counts are for physical words
+ * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ * - transfer count loaded to registers is 1 less than actual count
+ * - controller 2 offsets are all even (2x offsets for controller 1)
+ * - page registers for 5-7 don't use data bit 0, represent 128K pages
+ * - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ * Address mapping for channels 0-3:
+ *
+ * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * P7 ... P0 A7 ... A0 A7 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Address mapping for channels 5-7:
+ *
+ * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
+ * | ... | \ \ ... \ \ \ ... \ \
+ * | ... | \ \ ... \ \ \ ... \ (not used)
+ * | ... | \ \ ... \ \ \ ... \
+ * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * It is convenient to program the OATRAN register so that

+ *
+ * The only hard restrictions on the value of OATRAN is that

+ * addresses to fall within the lowest 512MB of
+ * PCI address space. This region is hardcoded
+ * for use as Athena PCI Host Controller target
+ * access memory space to the Athena's SDRAM.
+ *
+ * Note that OATRAN applies only to memory accesses, not
+ * to I/O accesses.
+ *
+ * To program OATRAN to make Athena virtual address space
+ * and PCI address space have the same values, OATRAN
+ * is to be programmed to 0xB8000000. The top seven
+ * bits of the value mimic the seven bits clipped off
+ * by the PCI Host controller.
+ *
+ * With OATRAN at the said value, when the CPU does
+ * an access to its virtual address at, say 0xB900_5000,
+ * the address appearing on the PCI bus will be

+ * SMP/VPE-safe functions to access "registers" (see note).
+ *
+ * NOTES:
+* - These macros use ll/sc instructions, so it is your responsibility to
+ * ensure these are available on your platform before including this file.
+ * - The MIPS32 spec states that ll/sc results are undefined for uncached
+ * accesses. This means they can't be used on HW registers accessed
+ * through kseg1. Code which requires these macros for this purpose must
+ * front-end the registers with cached memory "registers" and have a single
+ * thread update the actual HW registers.
+ * - A maximum of 2k of code can be inserted between ll and sc. Every
+ * memory accesses between the instructions will increase the chance of
+ * sc failing and having to loop.
+ * - When using custom_read_reg32/custom_write_reg32 only perform the
+ * necessary logical operations on the register value in between these
+ * two calls. All other logic should be performed before the first call.
+ * - There is a bug on the R10000 chips which has a workaround. If you
+ * are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
+ * to be non-zero. If you are using this header from within linux, you may
+ * include <asm/war.h> before including this file to have this defined
+ * appropriately for you.

+ * Notes:
+ * 1) The SPI registers are split into two blocks, one offset from the
+ * MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
+ * 0x68. The SPI driver definitions for the register must be aware
+ * of this.
+ * 2) The block copy engine register are divided into two regions, one
+ * for the control/configuration of the engine proper and one for the
+ * values of the descriptors used in the copy process. These have
+ * different base defines (CTRL_BASE vs DESC_BASE)
+ * 3) These constants are for physical addresses which means that they
+ * work correctly with "ioremap" and friends. This means that device
+ * drivers will need to remap these addresses using ioremap and perhaps
+ * the readw/writew macros. Or they could use the regptr() macro
+ * defined below, but the readw/writew calls are the correct thing.
+ * 4) The UARTs have an additional status register offset from the base
+ * address. This register isn't used in the standard 8250 driver but
+ * may be used in other software. Consult the hardware datasheet for
+ * offset details.
+ * 5) For some unknown reason the security engine (MSP_SEC_BASE) registers
+ * start at an offset of 0x84 from the base address but the block of
+ * registers before this is reserved for the security engine. The
+ * driver will have to be aware of this but it makes the register
+ * definitions line up better with the documentation.

+ * Some general notes:
+ *
+ * Register addresses are grouped by function and follow the order
+ * of the User Manual.
+ *
+ * For the most part, when there is more than one peripheral
+ * of the same type on the SOC, the constants below will be
+ * offsets from the base of each peripheral. For example,
+ * the MAC registers are described as offsets from the first
+ * MAC register, and there will be a MAC_REGISTER() macro
+ * to calculate the base address of a given MAC.
+ *
+ * The information in this file is based on the BCM1X55/BCM1X80
+ * User Manual, Document 1X55_1X80-UM100-R, 22/12/03.
+ *
+ * This file is basically a "what's new" header file. Since the
+ * BCM1250 and the new BCM1480 (and derivatives) share many common
+ * features, this file contains only what's new or changed from
+ * the 1250. (above, you can see that we include the 1250 symbols
+ * to get the base functionality).
+ *
+ * In software, be sure to use the correct symbols, particularly
+ * for blocks that are different between the two chip families.
+ * All BCM1480-specific symbols have _BCM1480_ in their names,
+ * and all BCM1250-specific and "base" functions that are common in
+ * both chips have no special names (this is for compatibility with
+ * older include files). Therefore, if you're working with the
+ * SCD, which is very different on each chip, A_SCD_xxx implies
+ * the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
+ * version.

+ * Some general notes:
+ *
+ * This file is basically a "what's new" header file. Since the
+ * BCM1250 and the new BCM1480 (and derivatives) share many common
+ * features, this file contains only what's new or changed from
+ * the 1250. (above, you can see that we include the 1250 symbols
+ * to get the base functionality).
+ *
+ * In software, be sure to use the correct symbols, particularly
+ * for blocks that are different between the two chip families.
+ * All BCM1480-specific symbols have _BCM1480_ in their names,
+ * and all BCM1250-specific and "base" functions that are common in
+ * both chips have no special names (this is for compatibility with
+ * older include files). Therefore, if you're working with the
+ * SCD, which is very different on each chip, A_SCD_xxx implies
+ * the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
+ * version.

+ * The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
+ * can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
+ * the LOCAL/current NODE. REMOTE means it is attached to a different
+ * node.(TBD - Need a way to treat ROUTER boards.)
+ *
+ * There are 2 different structures to represent these boards -
+ * lboard - Local board, rboard - remote board. These 2 structures
+ * can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
+ * Figure below). The first byte of the rboard or lboard structure
+ * is used to find out its type - no unions are used.
+ * If it is a lboard, then the config info of this board will be found
+ * on the local node. (LOCAL NODE BASE + offset value gives pointer to
+ * the structure.
+ * If it is a rboard, the local structure contains the node number
+ * and the offset of the beginning of the LINKED LIST on the remote node.
+ * The details of the hardware on a remote node can be built locally,
+ * if required, by reading the LINKED LIST on the remote node and
+ * ignoring all the rboards on that node.
+ *
+ * The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
+ * First board info on the remote node. The remote node list is

+ * Each BOARD consists of COMPONENTs and the BOARD structure has
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error
+ * information specific to the COMPONENT is present in the respective
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ *
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.

+ * SN0 (on a T5) Address map
+ *
+ * This file contains a set of definitions and macros which are used
+ * to reference into the major address spaces (CAC, HSPEC, IO, MSPEC,
+ * and UNCAC) used by the SN0 architecture. It also contains addresses
+ * for "major" statically locatable PROM/Kernel data structures, such as
+ * the partition table, the configuration data structure, etc.
+ * We make an implicit assumption that the processor using this file
+ * follows the R10K's provisions for specifying uncached attributes;
+ * should this change, the base registers may very well become processor-
+ * dependent.
+ *
+ * For more information on the address spaces, see the "Local Resources"
+ * chapter of the Hub specification.
+ *
+ * NOTE: This header file is included both by C and by assembler source
+ * files. Please bracket any language-dependent definitions
+ * appropriately.
+ */
+
+/*
+ * Some of the macros here need to be casted to appropriate types when used
+ * from C. They definitely must not be casted from assembly language so we
+ * use some new ANSI preprocessor stuff to paste these on where needed.
+ */
+
+/*
+ * The following couple of definitions will eventually need to be variables,
+ * since the amount of address space assigned to each node depends on
+ * whether the system is running in N-mode (more nodes with less memory)
+ * or M-mode (fewer nodes with more memory). We expect that it will
+ * be a while before we need to make this decision dynamically, though,
+ * so for now we just use defines bracketed by an ifdef.

+ * only one page long.
+ * data: The data segment follows next. We use current->end_text to
+ * current->brk to pick up all of the user variables, plus any memory
+ * that may have been sbrk'ed. No attempt is made to determine if a
+ * page is demand-zero or if a page is totally unused, we just cover
+ * the entire range. All of the addresses are rounded in such a way
+ * that an integral number of pages is written.
+ * stack: We need the stack information in order to get a meaningful

*
- * P3: Translation from irq 0x0d to mask 0x2000 is for MrCoffee.
+ * This ambiguity is resolved in the 'intr' property for device nodes
+ * in the OF device tree. Each 'intr' property entry is composed of
+ * two 32-bit words. The first word is the IRQ priority value, which
+ * is what we're intersted in. The second word is the IRQ vector, which
+ * is unused.
+ *
+ * The low 4 bits of the IRQ priority indicate the PIL, and the upper
+ * 4 bits indicate onboard vs. SBUS leveled vs. VME leveled. 0x20
+ * means onboard, 0x30 means SBUS leveled, and 0x40 means VME leveled.
+ *
+ * For example, an 'intr' IRQ priority value of 0x24 is onboard SCSI
+ * whereas a value of 0x33 is SBUS level 2. Here are some sample
+ * 'intr' property IRQ priority values from ss4, ss5, ss10, ss20, and

- *
- * This driver allows to upgrade microcode on Intel processors
- * belonging to IA-32 family - PentiumPro, Pentium II,
- * Pentium III, Xeon, Pentium 4, etc.
- *
- * Reference: Section 8.11 of Volume 3a, IA-32 Intel? Architecture
- * Software Developer's Manual
- * Order Number 253668 or free download from:
- *
- * http://developer.intel.com/design/pentium4/manuals/253668.htm

- *
- * 1.0 16 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Initial release.
- * 1.01 18 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Added read() support + cleanups.
- * 1.02 21 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Added 'device trimming' support. open(O_WRONLY) zeroes
- * and frees the saved copy of applied microcode.
- * 1.03 29 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Made to use devfs (/dev/cpu/microcode) + cleanups.
- * 1.04 06 Jun 2000, Simon Trimmer <simon@veritas.com>
- * Added misc device support (now uses both devfs and misc).
- * Added MICROCODE_IOCFREE ioctl to clear memory.
- * 1.05 09 Jun 2000, Simon Trimmer <simon@veritas.com>
- * Messages for error cases (non Intel & no suitable microcode).
- * 1.06 03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
- * Removed ->release(). Removed exclusive open and status bitmap.
- * Added microcode_rwsem to serialize read()/write()/ioctl().
- * Removed global kernel lock usage.
- * 1.07 07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
- * Write 0 to 0x8B msr and then cpuid before reading revision,
- * so that it works even if there were no update done by the
- * BIOS. Otherwise, reading from 0x8B gives junk (which happened
- * to be 0 on my machine which is why it worked even when I
- * disabled update by the BIOS)
- * Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
- * 1.08 11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
- * Tigran Aivazian <tigran@veritas.com>
- * Intel Pentium 4 processor support and bugfixes.
- * 1.09 30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
- * Bugfix for HT (Hyper-Threading) enabled processors
- * whereby processor resources are shared by all logical processors
- * in a single CPU package.
- * 1.10 28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
- * Tigran Aivazian <tigran@veritas.com>,
- * Serialize updates as required on HT processors due to speculative
- * nature of implementation.
- * 1.11 22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
- * Fix the panic when writing zero-length microcode chunk.
- * 1.12 29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
- * Jun Nakajima <jun.nakajima@intel.com>
- * Support for the microcode updates in the new format.
- * 1.13 10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
- * Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
- * because we no longer hold a copy of applied microcode
- * in kernel memory.
- * 1.14 25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
- * Fix sigmatch() macro to handle old CPUs with pf == 0.
- * Thanks to Stuart Swales for pointing out this bug.

+ * 1.0 16 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Initial release.
+ * 1.01 18 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Added read() support + cleanups.
+ * 1.02 21 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Added 'device trimming' support. open(O_WRONLY) zeroes
+ * and frees the saved copy of applied microcode.
+ * 1.03 29 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Made to use devfs (/dev/cpu/microcode) + cleanups.
+ * 1.04 06 Jun 2000, Simon Trimmer <simon@veritas.com>
+ * Added misc device support (now uses both devfs and misc).
+ * Added MICROCODE_IOCFREE ioctl to clear memory.
+ * 1.05 09 Jun 2000, Simon Trimmer <simon@veritas.com>
+ * Messages for error cases (non Intel & no suitable microcode).
+ * 1.06 03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
+ * Removed ->release(). Removed exclusive open and status bitmap.
+ * Added microcode_rwsem to serialize read()/write()/ioctl().
+ * Removed global kernel lock usage.
+ * 1.07 07 Sep 2000, Tigran Aivazian <tigran@veritas.com>

+ * 1.0 16 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Initial release.
+ * 1.01 18 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Added read() support + cleanups.
+ * 1.02 21 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Added 'device trimming' support. open(O_WRONLY) zeroes
+ * and frees the saved copy of applied microcode.
+ * 1.03 29 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ * Made to use devfs (/dev/cpu/microcode) + cleanups.
+ * 1.04 06 Jun 2000, Simon Trimmer <simon@veritas.com>
+ * Added misc device support (now uses both devfs and misc).
+ * Added MICROCODE_IOCFREE ioctl to clear memory.
+ * 1.05 09 Jun 2000, Simon Trimmer <simon@veritas.com>
+ * Messages for error cases (non Intel & no suitable microcode).
+ * 1.06 03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
+ * Removed ->release(). Removed exclusive open and status bitmap.
+ * Added microcode_rwsem to serialize read()/write()/ioctl().
+ * Removed global kernel lock usage.
+ * 1.07 07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
+ * Write 0 to 0x8B msr and then cpuid before reading revision,
