[RFC/PATCH 0/2] ARM: kirkwood: Add suspend/resume support

[Ezequiel Garcia]

This patchset implements a very basic suspend/resume support on
Kirkwood SoC's, based on the work of Simon Guinot.
Given the CPU itself is not stopped on suspend, but just sits
waiting for interruption, this is more similar to a standby-mode,
than to a real suspend-to-RAM.

In this opportunity, I'm sending this patchset as a very early RFC,
mostly to get some feedback on the first patch that implements the
suspend/resume procedures in the Feroceon CPU. This implemenation
has been copy-pasted from the one in ARM926, since I failed to spot
any differences between the CPU's on that matter.

Maybe someone more knowledgable can take a look and provide some insights.

This applies cleanly on top of v3.10-rc7 and has been tested on an
Openblocks A6 box. Notice that the network controller clock is not gated,
because the driver still needs proper suspend/resume operations.

Thanks a lot!
