Hi,
v3:
add comp-y Kbuild target
v2:
fix modules support
move compressed barebox to arch/<arch?compressed
rename target to zbarebox*
The following changes since commit 63ac9c743b1304b0b4b792643e4704394f6f8aeb:

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.

----------------------------------------------------------------
Jean-Christophe PLAGNIOL-VILLARD (11):
stddev: make it selectable via Kconfig
decompress_unlzo: define decompress_unlzo as decompress
compressed image: factorise compressor type
decompressor: import malloc/free implementation for linux 3.4
ARM: add early malloc support needed by the decompressor
compressed: rename barebox target to zbarebox and zbarebox.bin
compressed image: add gzip support
kbuild: Init all relevant variables used in kbuild files so
kbuild: add comp-y target
arm: use the new built-comp.o generated files
at91: add lowlevel init to the decompressor
