2012-01-05ARM: restart: remove the now empty arch_reset()Russell King
Remove the now empty arch_reset() from all the mach/system.h includes, and remove its callsite. Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.

2011-11-21ARM: restart: only perform setup for restart when soft-restartingRussell King
We only need to set the system up for a soft-restart if we're going to be doing a soft-restart. Provide a new function (soft_restart()) which does the setup and final call for this, and make platforms use it. Eliminate the call to setup_restart() from the default handler. This means that platforms arch_reset() function is no longer called with the page tables prepared for a soft-restart, and caches will still be enabled.

2011-09-26ARM: add an extra temp register to the low level debugging addruart macroNicolas Pitre
Some platforms (like OMAP not to name it) are doing rather complicated hacks just to determine the base UART address to use. Let's give their addruart macro some slack by providing an extra work register which will allow for much needed cleanups. This is basically a no-op as this commit is only adding the extra argument to the macro but no one is using it yet.

2011-08-12ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King
Rather than marking the mach/gpio.h header files which want to use the trivial GPIOLIB implementation, mark those which do not want to use it instead. This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.
