The ODROID-C2 requires its firmware to be cryptographically signed.

The vendor does provide a Linux x86-64 statically linked binary program
to do this, there is also a set of tools with source to do the same at:
<https://github.com/afaerber/meson-tools>. I only tried using the Linux
binary but it seems to work.

I built the firmware from a combination of mainline u-boot,
vendor u-boot: <https://github.com/hardkernel/u-boot>, and
vendor trusted firmware: <https://github.com/hardkernel/u-boot_firmware>.

Will probably need some help with creating packages to build this.

I now get the following, not sure yet what is causing the garbage output
from locore:
