2006-09-27[ARM] Separate page table manipulation code from bootmem initialisationRussell King2-34/+51
nommu does not require the page table manipulation code in the bootmem initialisation paths. Move this into separate inline functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-09-27[ARM] 3860/1: Versatile PCI config byte accessesPaul Brook1-1/+0
The ARM Versatile board PCI config space read routines are broken for byte accesses. The access uses a byte read, so masking the bottom two bits of the address is wrong. I guess this is a cut/paste error from the the halfword code which uses aligned word access+shift+mask.

2006-09-27[ARM] 3859/1: Fix devicemaps_init() XIP_KERNEL odd 1MiB XIP_PHYS_ADDR ↵George G. Davis2-2/+9
translation error The ARM XIP_KERNEL map created in devicemaps_init() is wrong. The map.pfn is rounded down to an even 1MiB section boundary which results in va/pa translations errors when XIP_PHYS_ADDR starts on an odd 1MiB boundary and this causes the kernel to hang. This patch fixes ARM XIP_KERNEL translation errors for the odd 1MiB XIP_PHYS_ADDR boundary case. Signed-off-by: George G.

2006-09-27[ARM] 3854/2: S3C2410 - add machine type for AML M5900 series (resubmitted)David Anders3-0/+253
Add the AML M5900 series to the list of supported machines in the arch/arm/mach-s3c2410 directory. This ensures the core peripherals are registered, and the timer source is configured. if selected in the kernel config the framebuffer registers and mtd partition information are set. This version of the patch has corrected formatting and removed the legacy procfs directory entry.

2006-09-25[ARM] 3789/4: Fix VFP emulation to ignore VECITR for scalar instructionGen FUKATSU3-71/+82
VECITR in Floating-Point Exception register indicates the number of remaining short vector iterations after a potential exception was detected. In case of exception caused by scalar instructions, VECITR is NOT updated. Therefore emulation for VFP must ignore VECITR field and treat "veclen" as zero when recognizing scalar instructing.

2006-09-25[ARM] 3792/2: Fix description of ZBOOT_ROM_BSSDan Fandrich1-5/+6
The documentation for the ZBOOT_ROM_BSS config option describes it as "The base address of 64KiB of read/write memory in the target for the ROM-able zImage..." In actuality, it requires more than 100 KiB of space in addition to enough space to hold the decompressed kernel. This patch fixes the description in the Kconfig file.

Fix thinko in the flush_ptrace_access() "if (expr)" for the ARM VIPT non-aliasing cache case. We only need to flush cache when VM_EXEC is set in vma->vm_flags but "if (expr) always evaluates to true on UP systems for the ARM VIPT non-aliasing cache case. Signed-off-by: George G.

2006-09-25[ARM] 3814/1: move 80200 dma_inv_range() erratum check out of lineLennert Buytenhek1-6/+52
On stepping A0/A1 of the 80200, invalidating D-cache by line doesn't clear the dirty bits, which means that if we invalidate a dirty line, the dirty data can still be written back to memory later on. To work around this, dma_inv_range() on these two processors is implemented as dma_flush_range() (i.e. do a clean D-cache line before doing the invalidate D-cache line.) For this, we currently have a processor ID check in xscale_dma_inv_range(), but a better solution is to add a separate cache_fns and proc_info for A0/A1 80200.
