Bootloader for mips

Hi all!

let's say that I want a very very very simple bootloader for MIPS that boots from flash roms, as trivial as 'start and go', without interaction, commands, etc.. any idea where I can find it?

Or at least how can I write it? (i.e. is there something else to do than setting up kernel parameters and jumping to the kernel start address?)

Thanks a lot,
Karl
