From 1eff66bbede9cab18f5cafcb376ebebdc6a3f95c Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Wed, 6 Feb 2013 18:25:36 +0000 Subject: [PATCH] ARM: pl01x debug code endian fix The PL01X debug code needs to take into account which endian mode the processor is running in. If it is big-endian, ensure the data is swapped appropriately. Note, we could do this slightly more efficiently if we have an macro to do the necessary swap for the bits used by test.
