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 v3: - Merged all "add to module device table" commits into a single commit which also changes the coreboot_driver struct to contain an id table and avoid unused variable warnings for the id tables. Changes in v2: - Added commits for vpd, memconsole and framebuffer drivers to add them to the module device table Reviewed-by: Brian Norris --- Nícolas F. R. A.
