The configs for cbmem coreboot entries are then enabled in the arm64 defconfig, as modules, to allow reading logs from coreboot on arm64 Chromebooks, which is useful for debugging the boot process. Changes in v2: - Added commits for vpd, memconsole and framebuffer drivers to add them to the module device table Nícolas F. R. A.
