Sorry. I though there was something at physical 0. Usually there's
the boot rom at 0.

I misinterpreted the 0xc for the virtual address, didn't think that
the jornada may have physical memory at 0xc. I apologize.

BTW: the ARM device I'm running today oppses when reading at offset 0
in /dev/mem, but it returns good data when using mmap() instead. I can
successfully read the boot flash.
