* Add multi images supportSascha Hauer2013-07-011-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the make infrastructure to build multiple SoC or board specific images from a single barebox binary. The basic idea is that we no longer have a single pbl, but instead multiple pbls, one per image if necessary. Each pbl is defined by its entry function so that each pbl can do exactly what a given board needs. Additionally the pbls together with a self extracting barebox binary can be encapsulated in specific image formats. squashed in build fixes from Lucas Stach for make version >= 3.82: Split Multimage Makefile rule in explicit and implicit parts Fixes build with make version >=3.82 Frome the make 3.82 NEWS file: * WARNING: Backward-incompatibility! In previous versions of make it was acceptable to list one or more explicit targets followed by one or more pattern targets in the same rule and it worked "as expected". However, this was not documented as acceptable and if you listed any explicit targets AFTER the pattern targets, the entire rule would be mis-parsed. This release removes this ability completely: make will generate an error message if you mix explicit and pattern targets in the same rule.

* ARM: Add relocatable binary supportSascha Hauer2013-03-071-0/+10
| | | | | | | | | | | | | | | | | | For making the same binary executable on different SoCs which have different DRAM addresses we have to be independent of the compile time link address. This patch adds relocatable binary support for the ARM architecture. With this two new functions are available. relocate_to_current_adr will fixup the binary to continue executing from the current position. relocate_to_adr will copy the binary to a given address, fixup the binary and continue executing from there. For the PBL and the real image relocatable support can be enabled independently. This is done to (hopefully) better cope with setups where the PBL runs from SRAM or ROM and the real binary does not.

* Add pre-bootloader (pbl) image supportJean-Christophe PLAGNIOL-VILLARD2012-08-033-0/+146
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>
