ok, so what's the "make" invocation to get one of those? i'm not a ppc expert so i don't know much about device trees. i tried the following:

so i'm open to suggestions.
In the cuboot section of arch/powerpc/boot/wrapper, add "*-tqm8xx" to the "*-mpc866ads|*-mpc885ads..." list.
ok, that's looking better as i now have the following:

which suggests it's safe to TFTP it to 200000 given its size and the load address, so ...

at which point i get the kernel uncompressing, followed by several lines of garbage, suggesting that perhaps my minicom setup is not right. any final suggestions about console port setup? i get the feeling i'm really close ...
