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.

	b7bcba8 Browse files » ARM: Enable mmu early ... This optionally enabled the MMU in the PBL or during early startup for the non PBL case. The regular MMU init code will pickup the already enabled MMU later. This might complicate debugging early code, so this has been made optional.

	93ef44f Browse files » ARM: Factor out early mmu code ... Move early mmu code to a separate file so that it can be used from the pbl and the regular image. 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

	5b03b81 Browse files » ARM: Add new entry point for barebox ... Memory is a precious resource, so it makes sense to make it available as early as possible. By definition the lowlevel init code already knows where to find memory because it's the lowlevel init code which sets up the memory. Until all boards are converted this new entry is just a fallback to the old entry point. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 4 Feb 2013

2012-10-04	6bb0652 Browse files » ARM pbl: actually create cached mappings in the decompressor ... We called create_sections with 4096MB as size argument, but create_sections expected the argument in bytes, so create sections was completely optimized away due to the size >>= 20. This patch changes the size argument to be in megabytes and adjusts map_cachable to pass the argument in megabytes.

This has the advantage that at least when a JTAG debugger is connected we can see what happens. Otherwise the code just jumps to NULL in case of an error.

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>.
