[U-Boot] [PATCH V4 00/11] ARM: OMAP3-DRA7: CP15 erratum workarounds and improvements

[Nishanth Menon]

The fourth incarnation of this series to address review comments on V3

With all the usual disclaimers and request to see V1 of the series for a
detailed blurb.. As usual additional testing preferred.. Sorry, I dont have
access to all possible variants atm..

changes since v3:
	- few corrections - i have tried to do a push-pop of register params.
	  hopefully, they should do the job
	- smc with a makefile handling of secure-ext enablement.. (stolen from kernel).

V2: http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/213060

I dont have access to other omap3 platforms to give a better coverage
