| * [ARM] nommu: confirms the CR_V bit in nommu modeHyok S. Choi2006-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In nommu mode, the exception vector location depends on the platforms. Some of the implementations may have some special exception control forwarding method in their ROM/flash and for some of them has its own re-mapping mechanism by the h/w. This patch introduces a special configuration CONFIG_CPU_HIGH_VECTOR which turns on the CR_V bit in nommu mode. The CR_V bit is turned off by default. This feature depends on CP15 and does not supported by ARM740. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: abort handler fixup for !CPU_CP15_MMU cores.Hyok S. Choi2006-09-28
| | | | | | | | | | | | | | | | | | | | There is no FSR/FAR register on no-CP15 or MPU cores. This patch adds a dummy abort handler which returns zero for the base restored Data Abort model !CPU_CP15_MMU cores. The abort-lv4t.S is still used with the fix-up for the base updated Data Abort model cores. Signed-off-by: Hyok S.

| * [ARM] nommu: add ARM946E-S core supportHyok S. Choi2006-09-27
| | | | | | | | | | | | | | | | | | | | | | This patch adds ARM946E-S core support which has typically 8KB I&D cache. It has a MPU and supports ARMv5TE instruction set. Because the ARM946E-S core can be synthesizable with various cache size, CONFIG_CPU_DCACHE_SIZE is defined for vendor specific configurations. Signed-off-by: Hyok S.

| * [ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPUHyok S. Choi2006-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Hyok S.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the static memory mapping for the currently-unused peripherals [Synchronous Serial, Timer/Counter unit], and for those drivers that already ioremap() their registers [UART]. Also, the Ethernet driver now uses the platform_device resources but doesn't yet use ioremap() so we need to pass it the virtual address instead of the physical address.
