2013-02-20	ARMV7: minor tweaks to inter-stage calling and payload handling.	Ronald G. Minnich
	Payloads, by design, can return. There's lots of mechanism in the payload code to support it, and the chooser payload relies on it. Hence, we should not mark the function call in exit_stage as noreturn. Not all ARM have unified caches, and it's not always easy to tell what to do. So we are very paranoid. Before we call between stages, we should carefully flush the dcache to memory and invalidate the icache. This may be more than is necessary on all architectures but it doesn't really hurt for the most part. So compile cache management code into all stages, and call the flush dcache/invalidate icache from all stages. Change-Id: Ib9cc625c4dfd2d7d4b3c69a74686cc655a9d6484 Signed-off-by: Ronald G.

2013-02-13	armv7: use start and size parameters in mmu_setup()	David Hendricks
	mmu_setup() was originally written in U-Boot to utilize board-specific global data. Since we're trying to avoid that, we added start and size parameters so that board-specific info can be passed in via mainboard code. Let's start using it that way.

2013-01-29	armv7: Clean up the mmu setup a bit	Ronald G. Minnich
	The previous incarnation did not use all of mmu_setup, which meant we did not carefully disable things before (possibly) changing them. This code is tested and works, and it's a bit of a simplification. Change-Id: I0560f9b8e25f31cd90e34304d6ec987fc5c87699 Signed-off-by: Ronald G.

2013-01-29	armv7: nuke global_data.h and remove some references to gd struct	David Hendricks
	This begins to remove references to global data which u-boot used. There are still many commented out references to gd-> and bd-> which we'll fix once we're happy with the replacements.

2013-01-29	armv7: Clean out weak symbols and unnecessary #ifdef's in cache files	David Hendricks
	This just removes unused code. If for some reason we don't want to initialize cache, then the CPU or mainboard specific init routines don't need to call these.
