Hi,
v2:
add custom cppflags to pbl
on arm always the garbage collector
please pull
The following changes since commit 9ab50e0b9cb6400a4442acd36c3d4b315685fa6a:

arm: allays enable the garbage collector for pbl (2012-07-28 20:14:45 +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.

Jean-Christophe PLAGNIOL-VILLARD (11):
kbuild: Init all relevant variables used in kbuild files so
kbuild: add pre-bootloader (pbl) target
Add pre-bootloader (pbl) image support
pbl: discard unwind symbol if enable in barebox
decompress_unlzo: define decompress_unlzo as decompress
decompressor: import malloc/free implementation for linux 3.4
ARM: add early malloc support needed by the decompressor
compressed image: add gzip support
at91: add lowlevel init to the pbl
kbuild: allow to have custom cppflags for pbl
arm: allays enable the garbage collector for pbl
Sascha Hauer (3):
Add compressed image support
only compress default env in uncompressed images
ARM: Separate assembler functions into their own section
