2012-03-13ARM: create a common IOMEM definitionRob Herring
Several platforms create IOMEM defines for casting to 'void __iomem *', and other platforms are incorrectly using __io() macro for the same purpose. This creates a common definition and removes all the platform specific versions. Rather than try to make linux/io.h and asm/io.h assembly safe, the assembly version of IOMEM is moved into asm/assembler.h.

2012-03-11ARM: iop13xx: fix missing declaration of iop13xx_init_earlyRob Herring

2012-03-11ARM: fix ioremap/iounmap for !CONFIG_MMURob Herring
With commit 4fe7ef3a081 (ARM: provide runtime hook for ioremap/iounmap), compiles with !CONFIG_MMU were broken. Rename nommu __iounmap to __arm_iounmap and add arch_ioremap_caller and arch_iounmap. Its not expected that these need to be overriden for !CONFIG_MMU, so setting the function ptrs has no effect in this case.

2012-03-06ARM: provide runtime hook for ioremap/iounmapRob Herring
We have compile time over-ride of ioremap and iounmap, but an run-time override is needed for multi-platform builds. This adds an extra function pointer check, but ioremap is not peformance critical. The option for compile time selection remains. The caller variant is used here to provide correct caller information as ARM can only support level 0 for __builtin_return_address.

2012-02-24ARM: OMAP2+: Limit omap_read/write usage to legacy USB driversTony Lindgren
Drivers should no longer use omap_read/write functions but instead use ioremap + read/write functions. As some USB legacy code is still shared between omap1 and omap2420, let's limit the omap_read/write to plat/usb.h. Note that the long term fix is to update the drivers to use ioremap and read/write functions. That can now be done as a separate patch series that is limited to the USB drivers. Also make sure the legacy omap1-keypad.c driver builds if selected for 2420 based systems. Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
