-gerrit commit f59f3567a06109971261c5d105b7332f4c331c94 Author: David Hendricks <[email protected]> Date: Sat Feb 9 16:42:23 2013 -0800 exynos/snow: set SPI clock rate in romstage main This moves the setting of SPI clock rate into romstage's main, which allows us to eliminate a bunch of dependencies from the bootblock (about 7KB worth).
