Building u-boot

[giuliomoro]

Using https://github.com/RobertCNelson/Bootloader-Builder with the patch below (unneeded, but makes things faster) allows to build a uboot that will boot the PocketBeagle. If we want to add our patches (e.g.: to change waiting time), they should go in patches/v2018.03 and maybe we can add our own profile to build.sh to apply the patches we need.

we can build from this https://github.com/giuliomoro/Bootloader-Builder/
./build.sh will do.

to create a patch:

• remove line 1048 git_cleanup from build.sh
• run ./build.sh once
• cd scratch/u-boot/
• apply your changes there, commit and then
  git format-patch -1 HEAD in the u-boot folder and then store the patch in Bootloader-Builder/patches/bela/
