I asked several times, if there's a way to differentiate those boards
(0020, 0030 and 0032) at runtime, but never get an answer. Of course
I'd like to see one U-Boot binary to rule them all, but I'm out of clue
there. Few people added to Cc...
Another approach might be to configure U-Boot using FDT and translate
that information into MACH_TYPE and kernel command line to support
non-device tree enabled kernels.
