Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections

2008-01-12T19:31:39Z

With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk

Move "ar" flags to config.mk to allow for silent "make -s"

Based on patch by Mike Frysinger, 20 Jun 2006

Add support for a saving build objects in a separate directory.

2006-09-01T17:49:50Z

Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

GCC-4.x fixes: clean up global data pointer initialization for all boards.

ARM memory layout fixes: the abort-stack is now set up in the correct RAM area, and the BSS is zeroed out as it should be. Furthermore, the magic variables 'armboot_end' and 'armboot_end_data' of the linker scripts are replaced by '__bss_start' and '_end', resp., which is a further step to eliminate unnecessary differences between the implementation of the CPU architectures.
