I finally had a chance to try this and my mx28evk can boot again with
your patch + the code above.

How do we handle this? Would you send a v2 with this additional code
or should I do it myself after your original patch in this thread gets
applied?

Also, please explain to the mortal folks what 'dram_vals[0x74 >> 2] =
0x0f02010a;' means.

It is not something very trivial to figure out :-)

Thanks,
