I mean the old version, not the new one. If you use MACHINE_START,
you cannot access the device tree data from the boot loader, which
means that none of the device drivers find their devices.

sorry i didn't get you.

DT is read to 0x3608000 by bootloader, and bootm has param "bootm
0x02008000 - 0x3608000" as:

bootcmd=mmc read 0 0x3608000 0x3780 0x80;mmc read 0 0x02008000 0x1800
0x1800;fdt addr 0x3608000;
fdt resize;bootm 0x02008000 - 0x3608000

kernel has been always able to read DT data from bootloader.

Ah, right. I had to read the initialition code again, my incorrect
assumption was that we could not use a machine_desc that is
declared with MACHINE_START() together with a flattened device tree.
