I'm trying to port Linux to a "non-stan- > dard" MPC860 board. I've ported linux to a few custom 860 boards. > Obviously, it does not provide the same > environment as the EPPC-Bug on the MBX860 boards.

I started loading a 'vmlinux' to address 0 and started at address 0x0c. That was just because I didn't like the things that was done in the boot-code for the zImage. The MBX board reads some stuff from the NVRAM and does a few wierd things. I've made a port to an ADS board from motorola, I've sent the patches to Dan Malek. I use the embedded-2.2.5 tarball, what code do you use? My patches are for the embedded-2.2.5 code. I've got a bootrom that loads a zImage or vmlinux from ATA-flash or romdisk. That might be a good start. Another thing - remember to read the errata for the 860. Revisions before C tend to have some problems. And 860T has still (B3) got problems.
