Re: [PATCH v5 04/25] mips: add support for noncached_alloc()

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 weijie.gao@mediatek.com

v5 changes: change KSEG1ADDR to CKSEG1ADDR v4 changes: new
