u-boot.git/cpu/mpc83xx, branch v1.3.2 Unnamed repository; edit this file 'description' to name the repository. PPC: Use r2 instead of r29 as global data pointer 2008-02-14T21:43:22+00:00 Wolfgang Denk wd@denx.de 2008-02-14T21:43:22+00:00 e7670f6c1e52ae6d2a43ff75a8bcfa7a5c86e47b R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections 2008-01-12T19:31:39+00:00 Wolfgang Denk wd@denx.de 2008-01-12T19:31:39+00:00 64134f011254123618798ff77c42ba196b2ec485 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 <wd@denx.de>
