ok I drop it
I put decompress_unlzo: define decompress_unlzo as decompress
first

and update the tag

The following changes since commit d8ddfd069f99428244aff34e2ccebe9ed6a6a7a3:

  decompress_unlzo: define decompress_unlzo as decompress (2012-07-30 16:23:54 +0800)

  arm: always enable the garbage collector for pbl (2012-07-30 16:24:26 +0800)

----------------------------------------------------------------
Add pre-bootloader (pbl) image support

This allows for creating a pre-bootloader binary for
 - nand boot
 - mmc boot
 - compressed image

Currently on the compressed image is implemented the boot really on current lowlevel
init support. In a second step this could be move to the pbl c code with generic framework.

The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.

The decompressor support lzo and gzip and allow to add easly more.
