All the current CP15 access codes in ARM arch can be categorized and conditioned by the defines as follows: Related operation Safe condition a. any CP15 access !CPU_CP15 b. alignment trap CPU_CP15_MMU c. D-cache(C-bit) CPU_CP15 d. I-cache CPU_CP15 && !( CPU_ARM610 || CPU_ARM710 || CPU_ARM720 || CPU_ARM740 || CPU_XSCALE || CPU_XSC3 ) e. alternate vector CPU_CP15 && !CPU_ARM740 f. TTB CPU_CP15_MMU g. Domain CPU_CP15_MMU h. FSR/FAR CPU_CP15_MMU For example, alternate vector is supported if and only if "CPU_CP15 && !CPU_ARM740" is satisfied. Signed-off-by: NHyok S.

By merging of uClinux/ARM, we need to treat various CPU cores which have MMU, MPU or even none for memory management. The memory management coprocessors are controlled by CP15 register set and the ARM core family can be categorized by 5 groups by the register ; G-a. CP15 is MMU : 610, 710, 720, 920, 922, 925, 926, 1020, 1020e, 1022, v6 and the derivations sa1100, sa110, xscale, xsc3. G-b. CP15 is MPU : 740, 940, 946, 996, 1156. G-c. CP15 is MPU or MMU : 1026 (selectable by schematic design) G-d. CP15 is exist, but nothing for memory managemnt : 966, 968. G-e. no-CP15 : 7tdmi, 9tdmi, 9e, 9ej This patch defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU. Thus the family can be defined as : - CPU_CP15 only : G-d - CPU_CP15_MMU(implies CPU_CP15) : G-a, G-c(selectable) - CPU_CP15_MPU(implies CPU_CP15) : G-b, G-c(selectable) - !CPU_CP15 : G-e Signed-off-by: NHyok S.

Since do_bad_area() always takes the currently active task and (supposed to) take the currently active MM, there's no point passing them to this function. Instead, obtain references to them inside do_bad_area(). Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

If we're going to have mmu.c for code which is specific to the MMU machines, we might as well move the other MMU initialisation specific code from mm-armv.c into this new file. This also allows us to make some functions static. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

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.

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: NGeorge G.

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.

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.

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.
