commit 9204b02dfc4abbc9974652c22c6c409c73301416 Author: Julius Werner jwerner@chromium.org Date: Wed Feb 17 16:12:46 2016 -0800
nyan: Fix timestamps and CBFS SPI integration
Nyan is an old board that was committed before several core code modernizations to timestamp and CBFS code. Not all of those later patches were correctly integrated with old boards like this, and the core code has evolved to a point where it doesn't actually boot anymore.
This patch fixes that issue and brings the Nyan boards more in line with how later ARM platforms look.
BRANCH=None BUG=None TEST=My Blaze boots again.
