From 0672a6497ec1ea59905487c01a65ffad79449538 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Tue, 13 Jul 2010 19:34:04 -0400 Subject: [PATCH] ARM ADI-V5: PIDs and CIDs are 8 bits Mask the upper bits after 32-bit reads. Alsoo revert the ugly changes to use PRIx32; just cast to unsized integers when printing (two chars not eight).
