The commit message says why - expected failure -- it is not an error.

It is checking a correct area that is expected to fail if the SPD setup
is wrong. Expected as in, if it is wrong, we try the memory setup for a
smaller amount for a different DBE61 variant.

It is not an error in the DBE61 case (co-incidentally the only use of
ram_check other than for debug purposes right now).

v3 doesn't have auto.c's, I assume you mean initram.c - it is checking
an area that is checkable, please refer to the thread "[PATCH 5/5] Be
less noisy in ram_check in non-debug loglevels" for a reasoning why it
is never necessary to show a message at BIOS_ERR console loglevel.
