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.

When an MPC5200 based board is used with SPL support, the main
U-Boot needs to clear the GD (global data) struct again.

Otherwise the generic board init code in board_init_f (when
CONFIG_SYS_GENERIC_BOARD is defined) will not initialize all
GD variables correctly. Resulting in a hangup on the a4m2k
board.

The UBI layer will disable much of its error reporting when it is
compiled into the linux kernel to avoid stopping boot.  We want this
error reporting in U-Boot since we don't initialize the UBI layer until
it is used and want the error reporting.

We force this by telling the UBI layer we are building as a module.

As in SAMA5D4 SoC, the gf table in ROM code can not be seen.
So, when we try to use PMECC, we need to build it when do
initialization.
Add a macro NO_GALOIS_TABLE_IN_ROM in soc header file. If it
is defined we will build gf table runtime.

The PMECC use the BCH algorithm, so based on the build_gf_tables()
function in lib/bch.c, we can build the Galois Field lookup table.
