In fact, there are messages there which probably point to the root cause. I've got a lot of messages like this, I'll just type in the first couple:
ack overflow in process c0162030, r1=c0162450 <2>Kernel stack overlow in process c0162030, r1=c01622b0 <4>Data machine check in kernel mode and lots more stuff like that but I presume the first messages are earliest and are the root cause.
Actually these are not the first messages; the ring buffer wrapped around. Try resetting the board faster, and/or increasing the log_buf size in your kernel configuration.
Without fully understanding this, this sounds like my stack isn't getting set up correctly. Is that U-Boot's responsibility? Any pointers as to where I'd start looking at that?
Linux will set up it's own stack; assuming you pass correct parameters to Linux (correct memory start address and size) it is most likely that your RAM is not working correctly.
