commit 4993cca28608b8fcb8c12b9aaccbf1ecf76878f6 Author: Ronald G. Minnich rminnich@google.com Date: Mon Oct 7 11:42:41 2013 -0700
nyan: Clock setup.
I cleaned up the clk_rst struct: no need to have an array for the source select because each thing is an individual entity.
There is a bit of a trick in here. I'm using macros to index arrays in the clk_rst struct. Simple reason: if people use the constants we get compile-time checking for simple errors.
init_pllx is fixed. The vendor table in u-boot was wrong.
