2014-08-07armv7: Fix dcache writethrough policy handlingDavid Hendricks
The "bufferable" bit was erroneously set for the writethrough policy making it the same as writeback.

2014-08-07exynos: Set up caching in the bootblock.Gabe Black
This improves firmware boot time substantially. Because cbmem isn't available yet, we need to allocate some space in sram for the ttb. Doing cache initialization in the bootblock means we can implement this once per CPU instead of once per mainboard.

This caused the machine to hang on resume. However, other bugs were preventing us from testing this properly earlier on so it went unnoticed until now.

2013-07-10ARMv7: flatten arch/armv7 source treeStefan Reinauer
With only 19 source files it doesn't make a whole lot of sense to create sub directories in arch/armv7, especially since the files were distributed somewhat randomly.
