Actually, limon will read the reset configuration word to find what the IMMR
should be, then changes it to 0xf0000000. If you flash limon and have the
reset conf word right, all will be well. If you download limon using the
vxWorks loader, then the reset conf word needs to set IMMR to 0x0f000000,
so the vxWorks loader and limon can agree.
