From 0f7b400f2e3497cf37758f4b14040930bea22391 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Sat, 9 Feb 2013 16:42:23 -0800 Subject: [PATCH] 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).
