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.

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>

This is needed to minimize io.h so the SoC specific io.h for ARMs can removed. Note that minimal driver changes for DSS and RNG are needed to include cpu.h for SoC detection macros.

Remove omap_{read,write}l() from the 24xx PM code. The clocksource code should now handle what this was supposed to do. Tested on N800 -- but it's hard to say whether this fixes anything.
