commit 4b1d8692dbcc46698b85c2047180f2b67d2c9099 Author: Aaron Durbin adurbin@chromium.org Date: Wed May 20 12:08:55 2015 -0500
assets: abstract away the firmware assets used for booting
As there can be more than one source of firmware assets this patch generalizes the notion of locating a particular asset. struct asset is added along with some helper functions for working on assets as a first class citizen.
