v3:
	add comp-y Kbuild target

v2:
	fix modules support
	move compressed barebox to arch/<arch?compressed
	rename target to zbarebox*

  at91: add lowlevel init to the decompressor (2012-07-25 15:45:40 +0800)

----------------------------------------------------------------
compressed: gzip support and cleanup

The follwing patch series add the support of GZIP

And allow now to link only what is need in the decompressor

This is needed if you want to compile a barebox with modules support

as we current rely on gcc and it's garbage colector to clean the non
needed object.

With modules support gcc will not do this.

This will allow to have a version of barebox shrink to the first
128KiB so it can fit in the first page of nand which is garanty
badblock free and then if we need more feature we will use modules
store in an other partitions.

Kbuild: Introduce built-comp to have related decompressor object across the
source tree.
