This doesn't work if the ATF BL31_BASE is 0x1000 instead of 0x10000,
but there are other reasons why 0x1000 doesn't work.  Tested this with
ATF v1.4 with BL31_BASE moved back to 0x10000, and that works fine.
So this is defenitely progress!  This allows me to build my own
firmware for the Firefly-RK3399 with a sane console speed of 115200.
