- Add Kconfig and Makefile options to use U-Boot as a payload. - Add Kconfig option for extra cbfstool command line arguments. - Add Kconfig & Makefile option to load the payload as a flat binary. - Add u-boot directory to .gitignore. This is currently working for X-86 only. Graphics worked in U-Boot correctly by initializing the VBIOS and setting up a console mode. Tested in QEMU and on Minnowboard Max. Got into U-Boot, have not booted an OS yet.
