[ARM] nommu: add ARM946E-S core support
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. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
