This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

find_tlb_idx() is called in board_early_init_r() on multiple boards.
The return value is not checked before being used to disable a TLB.
In normal case the return value wouldn't be -1. In case of a mis-
configuration during porting to a new board, checking the return value
may be helpful to reveal some user errors.

Add TLB mappings, board target options, and configuration items
need for SPI/SD boot.
Since P1022DS RevB board, the NOR flash have been changed to 16 bit/28bit
address flash, therefore, when SDHC/ESPI booting and access to eLBC,
the PMUXCR[0~1] must be set to 10b, and PMUXCR[9~10] must be set to
00b for them.
Configure the PX_BRDCFG0[0~1] to 10b which is connected to
SPI devices as SPI_CS(0:3)_B.

Most 85xx boards can be built as a 32-bit or a 36-bit. Current code sometimes
displays which of these is actually built, but it's inconsistent. This is
especially problematic since the "default" build for a given 85xx board can
be either one, so if you don't see a message, you can't always know which
size is being used. Not only that, but each board includes code that displays
the message, so there is duplication.
The 'bdinfo' command has been updated to display this information, so
we don't need to display it at boot time. The board-specific code is
deleted.

The clock-frequency property in an audio codec's device tree node is set to
the input clock frequency for that codec. On the Freescale P1022DS board,
the input clock is enabled only if the hwconfig 'audclk' option is set.
Therefore, the property should only be set in the device tree if the clock
is actually enabled.

This converts tsec to use the new PHY Lib. All of the old PHY support
is ripped out. The old MDIO driver is split off, and placed in
fsl_mdio.c. The initialization is modified to initialize the MDIO
driver as well. The powerpc config file is modified to configure PHYLIB
if TSEC_ENET is configured.

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

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

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.

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.
