This patch adds support for noncached_alloc() which was only supported by ARM platform. Unlike the ARM platform, MMU is not used in u-boot for MIPS. Instead, KSEG is provided to access uncached memory. So most code of this patch is copied from cache.c of ARM platform, with only two differences: 1. MMU is untouched in noncached_set_region() 2. Address returned by noncached_alloc() is converted using KSEG1ADDR() Signed-off-by: Weijie Gao <[email protected]> --- v5 changes: change KSEG1ADDR to CKSEG1ADDR v4 changes: new --- arch/mips/include/asm/system.h | 20 ++++++++++++++++ arch/mips/lib/cache.c | 43 ++++++++++++++++++++++++++++++++++ 2 files changed, 63 insertions(+)
