package/odroidc2-firmware: new package
The AmLogic Odroid C2 boards use an ATF version for which the source
code is not available. The mainline U-Boot documentation at
doc/board/amlogic/odroid-c2.rst details how to build a bootable U-Boot
image for this platform: it requires fetching the ATF binary files
from https://github.com/hardkernel/u-boot.git as well as a tool called
fip_create from the same repository.
This commit therefore implements a simple Buildroot package that
retrieves this repository, installs the firmware files, and
builds/installs the host fip_create utility.
This package really installs target images (firmware files) and one
host utility, so we had to take an arbitrary decision on whether it
should be a target package or a host package, and we've chosen to make
it a target package.
