From 493af3333813b4b8c1e1eddd71205a0c71b20f1f Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 16 Oct 2010 19:13:01 +0200 Subject: [PATCH 15/23] ARM: 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.
