3b258e2e58 Fix build issues cause by LDFLAGS_FINAL changes
Commit 6dc1ece "Introduce a new linker flag LDFLAGS_FINAL" modified a
number of Makefiles in a way that broke out-of-tree builds.  The
problem was that $(nandobj) was used before it got defined.

Fix this.

6dc1eceb9c Introduce a new linker flag LDFLAGS_FINAL
commit 8aba9dceeb
Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS

breaks the usage of --gc-section to build nand_spl. We still need linker option
--gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes
the --gc-sections to each uboot image.

To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace
PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

767589a7b2 powerpc/nand spl: link libgcc
Recent GCC (4.4+) performs out-of-line epilogues in some cases, when
optimizing for size.  It causes a link error for _restgpr_30_x (and similar)
if libgcc is not linked.

It actually increases size with very small binaries, due to the fixed size
of the out-of-line code, and not having any functions that actually need to
restore more than 2 or 3 registers.  But I don't see a way to turn it off,
other than asking GCC to optimize for speed -- which may also increase
size for some boards.

f1c574d400 83xx: Fix NAND_SPL link address
Apply the same fix for 83xx as was done for 85xx in commit
96196a1f75.

Without this, NAND SPLs are built with the text base intended for the main
image, resulting in a broken, very large u-boot-nand.bin.

The block of defines for NAND boot is moved closer to where
CONFIG_SYS_TEXT_BASE is defined.  We can't directly use
CONFIG_SYS_NAND_U_BOOT_DST in the definition of CONFIG_SYS_TEXT_BASE because
autoconf.mk will include the literal text "CONFIG_SYS_NAND_U_BOOT_DST",
but at least keep them close and point out that they're supposed to be
the same.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

ea0364f1bb Move lib_$ARCH directories to arch/$ARCH/lib
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk

This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.

1aada9cd64 Fix all linker scripts for older binutils versions (pre-2.16)
Commit f62fb99941 fixed handling of all rodata sections by using a
wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT()
and SORT_BY_NAME().  Unfortunately these functions were only
introduced with biunutils version 2.16, so the modification broke
building with all tool chains using older binutils.

This patch makes it work again.  This is done by omitting the use of
these functions for such old tool chains.  This will result in
slightly larger target binaries, as the rodata sections are no longer
in optimal order alignment-wise which reauls in unused gaps, but the
effect was found to be insignificant - especially compared to the fact
that you cannot build U-Boot at all in the current state.

As ld seems to have no support for conditionals we run the linker
script through the C preprocessor which can be easily used to remove
the unwanted function calls.

Note that the C preprocessor must be run with the "-ansi" (or a
"-std=") option to make sure all the system-specific predefined
macros outside the reserved namespace are suppressed. Otherise, cpp
might for example substitute "powerpc" to "1", thus corrupting for
example "OUTPUT_ARCH(powerpc)" etc.

Fix typo in makefile which broke out of tree builds.

Also use expolicit "rm" instead of "ln -sf" which is known to be

5bb907a492 mpc83xx: New board support for SIMPC8313
This patch will create a new board, SIMPC8313, from Sheldon Instruments.  This
board boots from NAND devices and is configureable for either large or small
page devices.  The board supports non-soldered DDR2, one ethernet port, a
Marvell 88E1118 PHY, and PCI host support.  The board also has a FPGA connected
to the eLBC providing glue logic to a TMS320C67xx DSP.
