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.

Since commit ddaf5c8f30
(patman: RunPipe() should not pipe stdout/stderr unless asked),
Patman spits lots of "Invalid MAINTAINERS address: '-'"
error messages for patches with global changes.
It takes too long for Patman to process them.
Anyway, "M: -" does not carry any important information.
Rather, it is just like a place holder in case of assigning

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.
The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.
After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

In the earlier patches, the SPL/TPL fraamework was introduced.
For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
the DDR according to the SPD and loads the final uboot image into DDR, then
jump to the DDR to begin execution.
For NAND booting way, the nand SPL has size limitation on some board(e.g.
P1010RDB), it can not be more than 4KB, we can call it "minimal SPL", So the
dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
and loads the final uboot image into DDR,then jump to the DDR to begin execution.
This patch enabled SPL/TPL for P1_P2_RDB to support starting from NAND/SD/SPI
flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
execute, so the section .resetvec is no longer needed.

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.

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.

change only the 517 board uses this so I have moved the ddr code

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.

When planning for more generalization and Makefile cleanup it became
obvious that the introduction of a separate CONFIG_MK_ name space for
config options that were set through scripting in the Makefile was
not a good idea.
Originally the idea was to provide a script-free approach to supply
configuration options - there was no real need for a separate name
space. But when we now convert the existing Makefile entries to make
use of this approach, it would mean that we have to touch a large
number of board config files and add #ifdef / #define sequences to
"convert" from the CONFIG_MK_ to the CONFIG_ name space.
It seems much cleaner to get rid of this somewhat arbitrary _MK
string now for the few boards that actually use it.
