From ad68bb9f7a3cd47396635a5e3895215af57579da Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 3 Nov 2010 16:29:35 +0100 Subject: ARM: pxa: Access SMEMC via virtual addresses This is important because on PXA3xx, the physical mapping of SMEMC registers differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx and PXA320, the PCMCIA driver was adjusted accordingly as well. Also, various places in the kernel had to be patched to use __raw_read/__raw_write.
