commit 9ea5184e85cb2e6e78ab397836dc49b0cc879cb7 Author: Ronald G. Minnich rminnich@gmail.com Date: Tue Jan 29 14:35:35 2013 -0800
Exynos5250: Get DDR3 working by changing what is compiled and add a function
This is a minor set of changes to get DDR3 going.
Move compilation of DDR3 startup to the romstage. Fix a prototype that was missing a void. Remove a function that is overly flexible, and even though it is overly flexible only actually can handle one type of RAM. Mainboards only support one type of DRAM, so create a function to explicitly initialize the type of DDR we have -- DDR3.
With these changes, and the previous changes, google snow is ready to run the ramstage.
