Clean and refactor the structure of the LinuxBoot payload integration, to make it more modular and readable. The kernel and initramfs should handled in separated makefiles. tested with: - qemu-i440fx (x86, x86_64) - cavium CN8100 (arm64) Change-Id: I41d0275a5f7efb920e881f43b0acda29f41ee221 Signed-off-by: Marcello Sylvester Bauer <info@marcellobauer.com> Reviewed-on: https://review.coreboot.org/c/29581 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Philipp Deppenwiese <zaolin.daisuki@gmail.com>
