Add a first bit of a framework. Builds the following parts, in

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.
