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.

ae6beb24d7 nand_spl: change out_be32 to raw_writel and depend on subsequent sync
This change reduces the SPL size by removing the redundant syncs produced
by out_be32 and just replies on one final sync

Done with:

sed -r '/in_be32/b; s/(out_be32)\(([^,]*),\s+(.*)\)/__raw_writel(\3, \2)/g' -i `git grep --name-only sdram_init nand_spl/`

8c454047fe nand_spl: update udelay for Freescale boards
Let's use the more appropriate udelay for the nand_spl. While we
can't make use of u-boot's full udelay we can atl east use a for
loop that won't get optimized away .Since we have the bus clock
we can use the timebase to calculate wall time.

Looked at reusing the u-boot udelay functions but it pulls in a lot
of code and would require quite a bit of work to keep us within the
very small space constrains we currently have

abbe536ebc powerpc/p1010rdb: nandboot: compare SVR properly
We were not comparing the SVRs properly previously. This comparison
will properly shift the SVR and mask off the E bit

This fixes the boot output to show the correct DDR bus width:

512 MiB (DDR3, 16-bit, CL=5, ECC off)

instead of

512 MiB (DDR3, 32-bit, CL=5, ECC off)

9c6b47d53e p1014rdb: set ddr bus width properly depending on SVR
Currently, for NAND boot for the P1010/4RDB we hard code the DDR
configuration. We can still dynamically set the DDR bus width in
the nand spl so the P1010/4RDB boards can boot from the same
u-boot image
