to a board should add a defconfig in mainboard/vendor/board/defconfig. I think that the defconfig should: 1. Use the ROM size that comes with the board 2. Enable compression 3. Not include a payload This will make it easy for buildrom or anyone who wants to build it manually to use lar to add their payloads. It also allows buildrom to keep the configs in the coreboot tree. The patch also adds mainboard/emulation/qemu-x86/defconfig Signed-off-by: Myles Watson <myles@pel.cs.byu.edu> Acked-by: Ward Vandewege <ward@gnu.org> git-svn-id: svn://coreboot.org/repository/coreboot-v3@578 f3766cd6-281f-0410-b1cd-43a5c92072e9
