2007-04-30[POWERPC] Remove the unused HTDMSOUND driverAdrian Bunk
Recently, someone fixed a syntax error in the HTDMSOUND driver introduced 4 years ago. Unfortunately not by trying to compile this driver for his hardware but by code inspection - which seems to be a strong indication that there are no users left for this OSS sound driver. This patch therefore removes it.

2007-04-30[POWERPC] New registration for common Xilinx Virtex ppc405 platform devicesGrant Likely
Currently virtex support in mainline make use of the infrastructure in arch/ppc/syslib/ppc_sys.c for registering common devices on virtex ppc405 platforms. The ppc_sys.c code is not well suited to the dynamic nature of FPGA designs and makes adding new board ports more complex. This patch adds a new listing of common devices which does not depend on the ppc_sys.c infrastructure.

2007-04-30[POWERPC] Rework Kconfig dependancies for Xilinx Virtex ppc405 platformGrant Likely
Reverse dependency order for Xilinx Virtex parts. For these parts, It makes more sense for boards/chips to specify which features they provide instead of the features listing the parts they are implemented in.

2007-04-27[POWERPC] Prepare for splitting up mmu.h by MMU typeDavid Gibson
Currently asm-powerpc/mmu.h has definitions for the 64-bit hash based MMU. If CONFIG_PPC64 is not set, it instead includes asm-ppc/mmu.h which contains a particularly horrible mess of #ifdefs giving the definitions for all the various 32-bit MMUs. It would be nice to have the low level definitions for each MMU type neatly in their own separate files. It would also be good to wean arch/powerpc off dependence on the old asm-ppc/mmu.h. This patch makes a start on such a cleanup by moving the definitions for the 64-bit hash MMU to their own file, asm-powerpc/mmu_hash64.h. Definitions for the other MMUs still all come from asm-ppc/mmu.h, however each MMU type can now be one-by-one moved over to their own file, in the process cleaning them up stripping them of cruft no longer necessary in arch/powerpc.

The uppermost part of memory is where u-boot puts the stack, so don't include that in the heap.

2007-04-27[POWERPC] bootwrapper: Fix array handling in dt_xlate_reg().Scott Wood
This fixes a few bugs in how dt_xlate_reg() handles address arrays: 1. copy_val() was copying into the wrong end of the array, resulting in random stack garbage at the other end. 2. dt_xlate_reg() was getting the result from the wrong end of the array. 3. add_reg() and sub_reg() were treating the arrays as little-endian rather than big-endian. 4. add_reg() only returned an error on a carry out of the entire array, rather than out of the naddr portion. 5. The requested reg resource was checked to see if it exceeded the size of the reg property, but not to see if it exceeded the size of the buffer.

2007-04-24[POWERPC] Abolish PHYS_FMT macro from arch/powerpcDavid Gibson
32-bit powerpc systems define a macro, PHYS_FMT, giving a printf format string fragment for displaying physical addresses, since most 32-bit powerpc platforms use 32-bit physical addresses but a few use 64-bit physical addresses. This macro is used in exactly one place, a rare error message, where we can solve the problem more simply by just unconditionally casting the address up to 64-bit quantity before formatting it. This patch does so, meaning that as we bring MMU definitions from asm-ppc over to asm-powerpc, cleaning them up in the process, we don't need to implement this ugly macro (which additionally has a very bad name for something global).

2007-04-24[POWERPC] Cleanup and fix breakage in tlbflush.hDavid Gibson
BenH's commit a741e67969577163a4cfc78d7fd2753219087ef1 in powerpc.git, although (AFAICT) only intended to affect ppc64, also has side-effects which break 44x. I think 40x, 8xx and Freescale Book E are also affected, though I haven't tested them. The problem lies in unconditionally removing flush_tlb_pending() from the versions of flush_tlb_mm(), flush_tlb_range() and flush_tlb_kernel_range() used on ppc64 - which are also used the embedded platforms mentioned above. The patch below cleans up the convoluted #ifdef logic in tlbflush.h, in the process restoring the necessary flushes for the software TLB platforms. There are three sets of definitions for the flushing hooks: the software TLB versions (revised to avoid using names which appear to related to TLB batching), the 32-bit hash based versions (external functions) amd the 64-bit hash based versions (which implement batching). It also moves the declaration of update_mmu_cache() to always be in tlbflush.h (previously it was in tlbflush.h except for PPC64, where it was in pgtable.h). Booted on Ebony (440GP) and compiled for 64-bit and 32-bit multiplatform.

2007-04-24[POWERPC] Re-organize Kconfig code for 4xx in arch/powerpcDavid Gibson
Now that we always take a device tree in arch/powerpc, there's no good reason not to allow a single kernel to support multiple embedded 4xx boards - the correct platform code can be selected based on the device tree information. Therefore, this patch re-arranges the 4xx Kconfig code to allow this. In addition we: - use "select" instead of depends to configure the correct config options for specific 4xx CPUs and workarounds, which makes the information about specific boards and CPUs less scattered. - Some old, unused (in arch/powerpc) config options are removed: WANT_EARLY_SERIAL, IBM_OCP, etc. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
