e76cd5d4cf 8xxx: Change all 8*xx_DDR addresses to 8xxx
There were a number of shared files that were using
CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and
several variants (DDR2, DDR3). A recent patchset added
85xx-specific ones to code which was used by 86xx systems.
After reviewing places where these constants were used, and
noting that the type definitions of the pointers assigned to
point to those addresses were the same, the cleanest approach
to fixing this problem was to unify the namespace for the
85xx, 83xx, and 86xx DDR address definitions.

This patch does:

s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g

All 85xx, 86xx, and 83xx have been built with this change.

13d1143ffb powerpc/mpc85xx/p2020rdb-pca: Use L2 SRAM for SPL boot
This allows DDR configuration to be deferred to the final U-Boot image,
which is able to make use of SPD data.  The SPL itself cannot use SPD due
to code size constraints.  It previously used fixed register values for
DDR configuration, and those values did not work on the p2020rdb-pca
board I tested with.  It's possible that different revisions of the board
require different settings.  Using SPD eliminates that problem.
