2013-03-07	a81ec02 Browse files » ARM: Add relocatable binary support ... 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.

Disabling the mmu can be dropped since the regular mmu code is now able to pickup an enabled mmu. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 4 Feb 2013

2012-09-27	faf7b7a Browse files » ARM: give boards control of the reset entry point ... On some SoCs (for example AM35xx), the ROM bootloader passes useful information in r0 when jumping to barebox. To avoid overwriting this in the generic reset code, we introduce common_reset as a C function and as an assembler macro. This is then called form the reset entry point (either in common or in board code). This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

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.
