From 6bee00dbbcb1e9feb0510e9a7104b4af00adc574 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 24 Oct 2008 10:21:45 -0700 Subject: [PATCH 01/16] [ARM] xsc3: revert writethrough memory-type encoding change Commit 40df2d1d "[ARM] Update Xscale and Xscale3 PTE mappings" was fingered by git-bisect for a boot failure on iop13xx. The change made L_PTE_MT_WRITETHROUGH mappings L2-uncacheable. Russell points out that this mapping is used for the vector page. Given the regression, and the fact this page is used often, restore the old behaviour.
