One step further - compiled ubldr as part of buildworld, tried, and
found I need ubldr.bin to start boot process, ubldr just keeps crashing
with following:

Booting from: mmc 0 ubldr
reading ubldr
235312 bytes read in 63 ms (3.6 MiB/s)

resetting ...

but ubldr.bin works (command typed manually):

=> fatload mmc 0 0x42000000 ubldr.bin
reading ubldr.bin

FreeBSD/arm U-Boot loader, Revision 1.2
(root at zeta.dino.sk, Tue Apr 19 06:33:11 CEST 2016)

DRAM: 512MB
MMC Device 1 not found
Number of U-Boot devices: 1
U-Boot env: loaderdev='mmc 0'
Found U-Boot device: disk
  Checking unit=0 slice=<auto> partition=<auto>... good.
Booting from disk0s1:
-
can't load 'kernel'

Type '?' for a list of commands, 'help' for more detailed help.
loader>

Now I can type loader command, so I can try to load kernel if I had one
(I tried to build it from stock FreeBSD sources, but something was
wrong, I must figure why buildkernel did not produce kernel... just
testing now, waiting where it breaks).
