2012-04-18ARM: fix __io macro for PCMCIARob Herring
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

This reverts commit 46bcfad7a819bd17ac4e831b04405152d59784ab. We aren't yet prepared to handle this commit - we need some sort of per-cpu idle state.

2012-01-20ARM: at91: fix at91rm9200 soc subtype handlingNicolas Ferre
Currently setting it to PQFP changes subtype to BGA as subtypes are swapped in at91rm9200_set_type(). Wrong subtype causes GPIO bank D not to work at all. After this fix, subtype is still set as unknown. But board code should fill it in with proper value. Another information is thus printed.

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.

Rather than using a private function pointer, use the existing arm_pm_restart function pointer instead.
