2007-04-27[AVR32] Clean up cpu identification and add features bitmapHaavard Skinnemoen
Clean up the cpu identification code, using definitions from <asm/sysreg.h> instead of hardcoded constants. Also, add a features bitmap to struct avr32_cpuinfo to allow other code to make decisions based upon what the running cpu is actually capable of.

2007-04-27[AVR32] Don't enable clocks with no usersHaavard Skinnemoen
Bring the code that sets the initial PM clock masks in line with the comment preceding it by only enabling clocks that have users != 0. Fix SM clock definition and avr32_hpt_init() so that the SM and TC0 clocks keep ticking. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Put cpu in sleep 0 when idle.Hans-Christian Egtvedt
This patch puts the CPU in sleep 0 when doing nothing, idle. This will turn of the CPU clock and thus save power. The CPU is waken again when an interrupt occurs. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Change system timer from count-compare to Timer/Counter 0Hans-Christian Egtvedt
Due to limitation of the count-compare system timer (not able to count when CPU is in sleep), the system timer had to be changed to use a peripheral timer/counter. The old COUNT-COMPARE code is still present in time.c as weak functions. The new timer is added to the architecture directory. This patch sets up TC0 as system timer The new timer has been tested on AT32AP7000/ATSTK1000 at 100 Hz, 250 Hz, 300 Hz and 1000 Hz. For more details about the timer/counter see the datasheet for AT32AP700x available at http://www.atmel.com/dyn/products/product_card.asp?part_id=3903 Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Add mach-specific KconfigHaavard Skinnemoen
Include at32ap-specific Kconfig file from top-level Kconfig file. The at32ap Kconfig is currently empty, but it will grow some machine- specific options soon. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Add nwait and tdf parameters to SMC configurationHans-Christian Egtvedt
Complete the SMC configuration code by adding nwait and tdf parameter. After this change, we support the same parameters as the hardware. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-27[AVR32] Add basic HMATRIX supportHaavard Skinnemoen
This adds register and clock definitions for the High-speed bus Matrix (HMATRIX) as well as a function that can be used to configure special EBI functionality like CompactFlash and NAND flash support. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

2007-04-26[SPARC64]: Privatize sun4u_get_pte() and fix name.David S. Miller
__get_phys is only called from init.c as is prom_virt_to_phys(), __get_iospace() is not called at all, and sun4u_get_pte() is largely misnamed. Privatize the implementation and helper functions of sun4u_get_phys() to mm/init.c, and rename to kvaddr_to_paddr(). The only used of this thing is flush_icache_range(), and thus things can be considerably further simplified. For example, we should only see module or PAGE_OFFSET kernel addresses here, so we don't need the OBP firmware range handling at all. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-26[SPARC64]: Kill _start[]/_end[] declarations in mm/init.cDavid S. Miller

2007-04-26[SPARC64]: Simplify read_obp_memory().David S. Miller
Kick out empty entries as soon as we spot them, and use memmove() instead of a silly loop to make the operation more clear. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-26[SPARC64]: Use SPARSEMEM_STATICDavid S. Miller
Decrease the SECTION_SIZE_BITS --> MAX_PHYSADDR_BITS range a little bit. The cost of going to SPARSEMEM_STATIC becomes 8K of BSS space, and in return we save a pointer dereferences on every page struct lookup. Even better we hit the main kernel image for the base address which is in a hugepage locked TLB entry. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-26[SPARC64]: Force dummy host controller onto bus zero.David S. Miller
This helps deal with the invisible bridge that sits between the host controller and the top-most visisble PCI devices on hypervisor systems. For example, on T1000 the bus-range property says 2 --> 4 and so there is a PCI express bridge at bus 2, devfn 0, etc. So if we don't force the dummy host controller to bus zero, we'll try to create two devices with the same domain/bus/devfn triplet. Also, add some more log diagnostics to make debugging stuff like this easyer. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-26[SPARC64]: Add dummy host controller to root of all PCI domains.David S. Miller

2007-04-26[SPARC64]: Fix sabre pci controllers with new probing scheme.David S. Miller
The SIMBA APB bridge is strange, it is a PCI bridge but it lacks some standard OF properties, in particular it lacks a 'ranges' property. What you have to do is read the IO and MEM range registers in the APB bridge to determine the ranges handled by each bridge. So fill in the bus resources by doing that. Since we now handle this quirk in the generic PCI and OF device probing layers, we can flat out eliminate all of that code from the sabre pci controller driver. In fact we can thus eliminate completely another quirk of the sabre driver. It tried to make the two APB bridges look like PBMs but that makes zero sense now (and it's questionable whether it ever made sense). So now just use pbm_A and probe the whole PCI hierarchy using that as the root. This simplification allows many future cleanups to occur. Also, I've found yet another quirk that needs to be worked around while testing this. You can't use the 'class-code' OF firmware property, especially for IDE controllers. We have to read the value out of PCI config space or else we'll see the value the device was showing before it was programmed into native mode. I'm starting to think it might be wise to just read all of the values out of PCI config space instead of using the OF properties. :-/ Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-26[SPARC64]: Internalize pci_memspace_mask.David S. Miller
The only user was bus_dvma_to_mem() which is no longer used by any driver, so kill that, and the export of pci_memspace_mask. The only user now is the PCI mmap support code. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-26[SPARC64]: Probe PCI bus using OF device tree.David S. Miller

2007-04-26[SPARC]: Use strcasecmp for OFW property name comparisons.David S. Miller
