Hi Roger,

I really appreciate the help!

I can "fix" the issue by just commenting out the "ECC uncorrectable
errors" print :-)

Interesting. With the "ecc" prints in U-Boot I also get some non-zero
values:

ecc: 0
ecc: 6bff997b
ecc: 6bff997b
ecc: 6bff997b

Once I'm booted, I can use nanddump. It seems like everything is correct
from the Linux side of things:

# nanddump -f mlo_dump /dev/mtd0

I'll take a look at am335x_spl_bch.c and look at what I'm doing different.
I was sad to see that `dump_stack()` didn't work off the bat for me.

All the CFG_* values should be identical for the SPL and U-Boot.

If you find anything let me know. I'll keep digging on my side as well.
