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>
