Yep. There are few issues out there with sleep34xx code.
	- Secure APIs
	- Current code needs to be cleaned up to remove
	unwanted registers save restore
	- Some part of the code on OMAP3 must be run from
	SRAM. It can't run from DDR
	- AUXCTLR, Diagnostic registers aren't accessible
	in secure mode.
	- L2 cache needs to be handled with secure APIs.
	- Code sequence needs to handle errata's handling
	which accesses OMAP PM registers.

Few of the above are getting addressed for this merge window.

So my plan was to take a look at generic suspend after the
merge window. By that time your generic stuff and omap
cleanup would have got merged hopefully.

Regards,
Santosh
