-gerrit commit da654974d7cd92946e363e024b126daf67e36c12 Author: Aaron Durbin <[email protected]> Date: Tue Jan 22 13:22:02 2013 -0600 cbfs: alternative support for cbfs_load_payload() In certain situations boot speed can be increased by providing an alternative implementation to cbfs_load_payload(). The ALT_CBFS_LOAD_PAYLOAD option allows for the mainboard or chipset to provide its own implementation. Booted baskingridge board with alternative and regular cbfs_load_payload().
