From af5703f2beb490fc700a30d0b87e84da0cf42086 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Mon, 25 May 2009 11:08:37 -0700 Subject: ARM: OMAP: Remove useless omap_sram_error function. This patch removes fixes omap_sram_error() function and replace the error paths with BUG_ON.

Note that after this patch there's no longer a hole between vmalloc space and the beginning of IO space on omap2 as the first virtual mapping starts at 0xd8000000. Also fold in a related change from Paul Walmsley to change the OMAP2_SRAM addresses accordingly.
