[U-Boot] [PATCH 04/10 v2] MPC512x: factor out common code
Wolfgang Denk

Sun Jun 14 20:58:47 CEST 2009
Now that we have 3 boards for the MPC512x it turns out that they all
use the very same fixed_sdram() code.
This patch factors out this common code into cpu/mpc512x/fixed_sdram.c
and adds a new header file, include/asm-ppc/mpc512x.h, with some
macros, inline functions and prototype definitions specific to MPC512x
systems.

v2: reposted in context with remaining patches of this series;
changed to use common spelling for CPU/board names.
