We've been utilizing board_lmb_reserve to reserve the boot page for MP
systems. We can just move this into arch_lmb_reserve for 85xx & 86xx
systems rather than duplicating in each board port.

The ngPIXIS is an FPGA used on the reference boards of most Freescale PowerPC
SOCs. Although programming the ngPIXIS is mostly standard on all boards that
have it, the P1022DS is unique in that the ngPIXIS needs to be programmed in
"indirect" mode whenever the video display (DIU) is active.
To support indirect mode, and to make it easier to support other quirks on
future reference boards, the low-level ngPIXIS functions are all marked as
weak, so that board-specific code can override any of them. We take advantage
of this feature on the P1022DS, so that we can properly reset the board when
the DIU is active.

Rather than defining it config.mk we can set it in config.h and remove
config.mk from several boards that don't need it.
We mimic what 4xx does and introduce CONFIG_RESET_VECTOR_ADDRESS for
config.h to set.

Since all the PCIe controllers are connected over SERDES on the SoCs we
can utilize is_serdes_configured() to determine if a controller is
enabled. After which we can setup the ATMUs and LAWs for the controller
in a common fashion and allow board code to specify what the controller
is connected to for reporting reasons.
We also provide a per controller (rather than all) for some systems that
may have special requirements.
Finally, we refactor the code used by the P1022DS to utilize the new
generic code.

Correct initdram to use phys_size_t to represent the size of
dram; instead of changing this all over the place, and correcting
all the other random errors I've noticed, create a
common initdram that is used by all non-corenet 85xx parts. Most
of the initdram() functions were identical, with 2 common differences:
1) DDR tlbs for the fixed_sdram case were set up in initdram() on
some boards, and were part of the tlb_table on others. I have
changed them all over to the initdram() method - we shouldn't
be accessing dram before this point so they don't need to be
done sooner, and this seems cleaner.
2) Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale
errata document. It also looks like some of the versions were
buggy, and, depending on timing, could have resulted in the
DDR controller being disabled. This seems bad.
The xpedite boards had a common/fsl_8xxx_ddr.c; with this
change only the 517 board uses this so I have moved the ddr code
into that board's directory in xpedite517x.c

On the P1022, the pins which drive the video display (DIU) are muxed with the
local bus controller (LBC), so if the DIU is active, the pins need to be
temporarily muxed to LBC whenever accessing NOR flash.
The code which handled this transition is checking and changing the wrong
bits in PMUXCR.
Also add a follow-up read after a write to NOR flash if we're going to
mux back to DIU after the write, as described in the P1022 RM.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Clean up Makefile, and drop a lot of the config.mk files on the way.
We now also automatically pick all boards that are listed in
boards.cfg (and with all configurations), so we can drop the redundant
entries from MAKEALL to avoid building these twice.

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.

The Freescale P1022DS can use either a 12.288MHz or a 11.2896MHz reference
clock for the audio codec, but by default both are disabled. Add a 'audclk'
hwconfig option that allows the user to choose which clock he wants.
The 12.288MHz clock allows the codec to use sampling rates of 16, 24, 32, 48,
64, and 96KHz. The 11.2896 clock allows 14700, 22050, 29400, 44100, 58800, and
88200Hz.
Also configure a pin muxing to select some SSI signals, which will disable
I2C1.

On the Freescale P1022, the DIU and the LBC share address pins, which means
that when the DIU is active (e.g. the console is on the DVI display), NOR flash
cannot be accessed. So we use the weak accessor function feature of the CFI
flash code to temporarily switch the pin mux from DIU to LBC whenever we want
to read or write flash. This has a significant performance penalty, but it's
the only way to make it work.
This change allows the 'saveenv' command to work when the video display is
enabled. Erasing flash and writing to flash (with the 'cp' command) works,
but reading from flash (with the 'md' and 'cp' commands) does not. Also, while
flash is being written, the video display will be blank.

Previously we used an alias the pci node to determine which node to
fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to
find the node to update.
Additionally, we replace the code in each board with a single macro call
that makes assumes uniform naming and reduces duplication in this area.
