Do you know what would cause this?
I've configured a board to console off of SMC1 (ttyCPM0) and on 1
board it works fine, however a new revision of the board I get the
following result and lose the console. Both boards have "exact"
versions of the kernel and u-boot.
BAD: console handover: boot [udbg0] -> real [tty0]
GOOD: console handover: boot [udbg0] -> real [ttyCPM0]
IMMRBASE is e0000000
CONFIG_PPC_EARLY_DEBUG_CPM=y
CONFIG_PPC_EARLY_DEBUG_CPM_ADDR=0xe0000888
doesn't WORK:
