Hi,

Some platforms need the ability to ioremap memory for use with small
chunks of code, like in certain PM applications that run from sram.

This series provides a common way to call an arch's ioremap_exec, which
currently only exists for ARM, so that we can use it in the generic
sram driver in a forthcoming patch.

This patch is part of a patch series split into several smaller sets
for introducing suspend on AM335x. I plan to use it to copy several
pieces of ASM code from an EMIF driver and the SoC PM code to run from
SRAM on the SoC. I have pushed a branch here [1] based on v3.18-rc6
with all required patches so that the higher level plan for these
patches can be seen.

Regards,
Dave
