* Add pre-bootloader (pbl) image supportJean-Christophe PLAGNIOL-VILLARD2012-08-031-0/+127
This allows for creating a pre-bootloader binary for - nand boot - mmc boot - compressed image The pbl will be incharge of the lowlevel init if needed. The barebox will skip it. Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and implement a dummy panic. For now on introduce dummy zbarebox* targets and c code that will contain later the decompressor. This only implemeted on ARM. This patch is based on Sascha Hauer <s.hauer@pengutronix.de> Add compressed image support patch Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
