u-boot: 2017.11 -> v2018.03-rc3

[bendlas]

this includes qemu-aarch64 support

Motivation for this change

I needed an updated u-boot for running my rpi3 sdcard with qemu. I figured I'd push it upstream right away.

Whether we can merge this as an -rc or not, I also wanted to document the patch I updated: It's based on dezgeg/u-boot@pythonpath-2018-03, but also accounts for u-boot/u-boot@15b97f5#diff-44b7a4b99d947fe1c4a313c4d890d8b6R384

cc @dezgeg does this look right to you?

This could be ubootQemuAarch64, in Nixpkgs naming 'Arm' always stands for the 32-bit one.

I also wanted to document the patch I updated: It's based on dezgeg/u-boot@pythonp, but also accounts for u-boot/u-boot@15b97f5#diff-44b7a4b99d947fe1c4a313c4d890d8b6R384

Thanks for the fix, I will squash that in my U-Boot patch branch for 2018.03.

As the 2018.03 upstream release is only a week away, let's wait for that, then have #36232 adjusted for 2018.03, then finally the ubootQemuAarch64 change.

U-Boot 2018.03 and ubootQemuAarch64are now in master.
