# if cross compiling, export GCC5_AARCH64_PREFIX=<whatever your toolchain>
# then, in edk2 dir, source edksetup.sh (--reconfig if you rerun at some later point, and might be using a different toolchain)
# then build -a AARCH64 -t GCC5 -p EmbeddedPkg/EmbeddedPkg.dsc -m EmbeddedPkg/Application/ConfigTableLoader/DtbLoader.inf
# use -b DEBUG or -b RELEASE to build with/without debug info and extra printouts

# https://eciton.net/~leif/DtbLoader.efi now works as expected - installing persistently is still manual from UEFI Shell
# source pushed to http://git.linaro.org/people/leif.lindholm/edk2.git/log/?h=dtbloader
# installation instructions - 1) copy driver to somewhere on the same filesystem the windows loader resides (this is FS3: when I boot with just the Shell USB key inserted), and the .dtb to the same directory, called my.dtb   2) bcfg driver add 1 <driver image> "<descriptive name>"
