ef123c5253 Refactor linker-generated arrays
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.

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.

59629c2897 spl/mpc85xx: move udelay to cpu code
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.

8bc50f0b6d powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxx
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.

a6d0f62a0c nand_spl: fix u-boot.lst breakage
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.

97b24d3d51 common: Add symbol handling for generic lists into Makefile
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.

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
