From 233fd64e7f42a7b8e827ee02528474e0fabfebdc Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Mon, 19 Oct 2009 15:25:31 -0700 Subject: omap: Split OMAP2_IO_ADDRESS to L3 and L4 This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to reclaim more IO space. The omap_read*() and omap_write*() functions will work only over L4 address space. Current omap kernel stack uses these functions only to access registers over L4 io address space Note that these macros should only be used when ioremap does not work. Please use ioremap instead in all new code.
