Subject: ARM: 6445/1: fixup TCM memory types
X-Git-Tag: v2.6.37-rc1~23^2~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f444fce3c0aa199facc8c2be7635a4a82b84b71e;p=platform%2Fkernel%2Flinux-exynos.git

ARM: 6445/1: fixup TCM memory types

After Santosh's fixup of the generic MT_MEMORY and
MT_MEMORY_NONCACHED I add this fix to the TCM memory types.
The main change is that the ITCM memory is L_PTE_WRITE and
DOMAIN_KERNEL which works just fine. The changed to the DTCM
is just cosmetic to fit with surrounding code.
