* ARM pbl: generate zbarebox.map in $(obj)Sascha Hauer2012-08-121-1/+1
| | | | | | | | All other linker generated files are there, too, so it seems logical to put the map file there aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

* Add compressed image supportJean-Christophe PLAGNIOL-VILLARD2012-08-031-0/+1
| | | | | | | | | | | | | | | | | | This allows for creating a lzo compressed binary unsing the pbl. Only copy the piggydata if needed. Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option In some case we need to copy the PIGGYDATA as the link address as example we run from SRAM and shutdown the SDRAM/DDR for reconfiguration but most of the time we just need to copy the executable code. based on Sascha Hauer Add compressed image support Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

* Add pre-bootloader (pbl) image supportJean-Christophe PLAGNIOL-VILLARD2012-08-032-0/+98
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>
