Hello,
The following patches (in subsequent mails) make DBE61A memory setup work for me, while keeping DBE61C working as well from the same build result ROM.
It appears to pass memtest86+ as long as I tested (at least one full pass for each), but only if it starts up. Sometimes it gives me "Unexpected Interrupt - Halting" at start, but memtest86+ with serial port support compiled in is known to be cranky like that. Either way, before these patches it wouldn't even reach the payload anyway on DBE61A.
