> 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.
