Martin Roth 22aa9e3fcc u-boot: Make sure targets aren't duplicated
When U-Boot isn't selected as a payload, two of the targets:
$(project_dir): and $(project_dir)/$(TAG-y) evaluated to the same
value, generating a make warning when running a clean.  By adding
additional text to the file that is created, this is avoided.

Gets rid of these warnings:
Makefile.inc:54: warning: overriding commands for target `u-boot'
Makefile.inc:37: warning: ignoring old commands for target `u-boot'

Martin Roth dbae4d03ef Payloads: Add U-Boot as a coreboot-payload
- 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.
