H A DREADME.standalonee7670f6c1e52ae6d2a43ff75a8bcfa7a5c86e47b Thu Feb 14 15:43:22 CST 2008 Wolfgang Denk <wd@denx.de> PPC: Use r2 instead of r29 as global data pointer

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.
