I'd noted in email that arch/mips/boot/vmlinux.bin is looks like the
stripped file we were looking for.  But it doesn't load:

RedBoot> load -m tftp -h 192.168.1.6 mthebeau/vmlinux.bin
Unrecognized image type: 0x0

I was able to load the larger vmlinux and boot it.

And as previously noted by ,  using
tmp/sysroots/x86_64-linux/usr/bin/mips32-poky-linux/mips-poky-linux-strip would
get a bootable image as well from the vmlinux.

I'll try to figure out what the difference is between that and vmlinux.bin.
