Hardware / Coreboot - Aaron Durbin [chromium.org] - 22 April 2015 08:38 UTC

Instead of always loading romstage from cbfs provide a way, similar to ramstage and payload, for other program loaders to intervene. For now, only the cbfs loader is consulted.

TEST=Booted to end of ramstage on qemu-armv7
