From c06015148fa9a3cc452ec7121b8c3f59f4a7d6ac Mon Sep 17 00:00:00 2001 From: Paul Brook Date: Sun, 24 Sep 2006 16:54:40 +0100 Subject: [PATCH] [ARM] 3860/1: Versatile PCI config byte accesses The ARM Versatile board PCI config space read routines are broken for byte accesses. The access uses a byte read, so masking the bottom two bits of the address is wrong. I guess this is a cut/paste error from the the halfword code which uses aligned word access+shift+mask.
