Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.
Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

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.

It applies to non-Freescale 85xx boards as well as Freescale boards,
so it doesn't belong in board/freescale. Plus, it needs to come out
of nand_spl if it's to be used by the new SPL.

It's arch code and not a driver, so move it where it belongs. When it
originally went into drivers/misc there was no 8xxx CPU directory.
This will make new-SPL support a little easier since we can keep the CPU
stuff together and not need to pull stuff in from drivers/misc.

Commit 97b24d3d51 "common: Add symbol
handling for generic lists into Makefile" introduced build errors in many
nand_spl targets, complaining of a missing u-boot.lst. When not doing an
out-of-tree build, $(obj) expands to nothing, so GCC ended up being given
-I with no argument (or rather, -ansi was the argument). The failure
didn't show up during a -j1 build because it was picking up the non-SPL
version of u-boot.lst.

This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.
The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .
Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

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/`
