accordance to the newboot document: * reset vector (16 bytes) * vpd (240bytes) * boot block (8k - 256b) * lar archive (256-8 k) The boot block is kind of simple, still. It enables pmode, car, and starts looking for an initram module in the lar archive. Note: This doesnt do much at the moment, as gas seems to produce buggy code in init.S. Take this as a suggestion of how it might work and please provide patches fixing it and bringing it into shape. Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Ronald G.
