Set Registers for VR4181A

Set Registers for VR4181A

[Julian Scheel]

Hi all,

as I wrote a few weeks ago I have a NEC VR4181A-Board, on which I want to get 
linux running. Currently I have a kernel which should work, but it can't 
boot, since linux seems to expect that the registers have been already set by 
the bootloader. Since the used bootloader is a very small one which only 
proceeds the given files (written by a friend of me) it didn't do this job, 
so linux tries to access registers, which are not set yet.

So I need a bootloader which can do the job and works with my CPU/Board. Can 
someone give me a hint which one to use?

Grüße,
Julian

Fixinging the few assumptions that Linus is making about the initializaton
state of the machine should be fairly easy.

I assume you mean Linux :)
