Actually, barebox is looking for a kernel named zImage-cfa10036 for all
the cfa-10036 based boards (that means all the crystalfontz boards for
now). Then, it is reading an eeprom to know what exactly is the board
and will load the DT accordingly. I don't have to change
COMPATIBLE_MACHINE because I'm adding cfa10036 to the MACHINEOVERRIDES
for those cfa-10036 based boards.
