This seems to work!

I have some more problems with the chip at present. I managed to build a
kernel, but booting won't work.
I use the NEC Bootloader, and load the Image over a serial-connection to the
Ram (address 0x8010000). The bootloader set the INTERNAL_REGISTERS_BASE to
0xab000000. If I understand the starting-process, the kernel normally
searches it at 0xbfa00000 which is the address, before the Bootloader changes
it. This is set in include/asm-mips/nile4.h . It gets changed to 0x0a000000
(set it smvr4181a.h).
Now I change the address in nile4.h to 0xab000000, so that the kernel should
use the correct address and then changes it to his 0x0a000000.
I think this is the problem, because I get absolutely no output after the
binary-download finished and should start.
Hopefully you can follow my explanation of the problem (c:
