u-boot.git/doc/README.standalone, branch v2009.11 Unnamed repository; edit this file 'description' to name the repository. Blackfin: change global data register from P5 to P3 2009-09-02T09:14:02+00:00 Robin Getz robin.getz@analog.com 2009-08-17T15:23:02+00:00 c4db335c2e0805e1ce4c33d278b77492c0812353 Since the Blackfin ABI favors higher scratch registers by default, use the last scratch register (P3) for global data rather than the first (P5). This allows the compiler's register allocator to use higher number scratch P registers, which in turn better matches the Blackfin instruction set, which reduces the size of U-Boot by more than 1024 bytes...

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>
