Greetings

Subject is a mpc86x based project.

Up until now I've been using an eval board which boots low (from 0x100) but to save parts on the target hardware I'd like to boot high from 0xfff00100 so I don't have to set IIP (default vectors) or ISB (default IMMR) in the hardware configuration word.

Can someone suggest an already implemented port of u-boot that starts from the high vector so I can get an idea of how to structure the linker control file so that start.o is *NOT* at the beginning but someplace up the image.

OR

Can I start execution with IMMR at 0x000000000 (by not setting ISB in the config word) and still run code from 0x100 (so I only have to pull up IIP at reset).
