Um, yeah.

You're triggering the gdb stub in RedBoot, which means that the kernel
is aborting, and pretty early on.  There is only an 8 MB contiguous chunk
starting at address 0x0, and your ending address is very close to that ...
I am almost certain that the BSS extends beyond the 8MB boundary.

A little while back I committed a change to the kernel config file for
the TS-7200 that trims a bunch of the fat from the kernel.  Sadly,
those changes didn't make it into 5.0.1.  If you're up to it, you can
cross-compile a new TS_7200 kernel with a bunch of the stuff commented
out you don't need (really, it's not very hard).  If that's beyond you,
I could probably compile you a new INSTALL kernel, but I'm kinda busy
right now.
