From 2909df32ac0b1cb6d6afe155232e2404ffad3f65 Mon Sep 17 00:00:00 2001

Subject: Move CBFS files to GRUB memdisk, except grub.cfg and grubtest.cfg

Set the GRUB configs to use (memdisk) instead of (cbfsdisk) for
these files.

This reduces the space used in CBFS because coreboot compresses
it's payloads with LZMA by default.

Most users will only want to use cbfstool to modify the grub.cfg
or grubtest.cfg.
