2012-03-06ARM: kill off __mem_pciRob Herring
__mem_pci is only used to enable readl/writel and friends. Just condition this on readl being defined and remove all the __mem_pci defines.

2012-03-06ARM: make mach/io.h include optionalRob Herring
Add a kconfig option NEED_MACH_IO_H to conditionally include mach/io.h. Basing this on CONFIG_PCI and CONFIG_ISA doesn't quite work. Most ISA platforms don't need mach/io.h, but ebsa110 does. Most PCI platforms need mach/io.h for now, but ks8695 doesn't which means i/o accesses are broken.

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>
