This prevents ETM stalls whenever core enters OFF mode. Original patch
author is Richard Woodruff .
This version of the patch makes use of the ETM OS save/restore mechanism,
which takes about 55 words in omap3_arm_context[] instead of 128. Also,
saving ETM context can be switched on/off at runtime

Oops, I wanted to resend the previous patch, but it's getting
This adds a sysfs file at /sys/power/coresight_save which is used to
control if the ETM and debug components' states should be saved and
restored across OFF modes.

Hi,
Just for the record, I found a problem in this patch. The next patch
in the series overrides it, so it's not that important, unless
somebody picks only this patch.

Hi,
While investigating a bug in maemo[1] I found that this patch triggers
it, I think I found the reason.
It probably doesn't matter for upstream anymore.

This adds a sysfs file at /sys/power/coresight_save which is used to
control if the ETM and debug components' states should be saved and
restored across OFF modes.

These addresses are also needed for the OFF code to save/restore the
contexts of the EMU peripherals correctly.

The DMA coherent remap area is used to provide an uncached mapping
of memory for coherency with DMA engines. Currently, we look for
any free hole which our allocation will fit in with page alignment.
However, this can lead to fragmentation of the area, and allows small
allocations to cross L1 ent
