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().
