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
a new board maintainer. Let's comment out.
This commit can be reproduced by the following command:
find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/'

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.
We can delete the ones in arch and board Kconfig files.
This commit can be easily reproduced by the following command:

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.
TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

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/.

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.

With this, fixup a trivial build error of get_effective_memsize needing
to be updated in the new board/freescale/p1010rdb/spl.c
Signed-off-by: Tom Rini <trini@ti.com>
In the previous patches, we introduced the SPL/TPL fraamework.
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 8KB, 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 P1010RDB 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.

Since pins multiplexing, SDHC shares signals with IFC, with this patch:
To enable SDHC in case of NOR/NAND/SPI boot
a) For temporary use case in runtime without reboot system
run 'mux sdhc' in u-boot to validate SDHC with invalidating IFC.
b) For long-term use case
set 'esdhc' in hwconfig and save it.
To enable IFC in case of SD boot
a) For temporary use case in runtime without reboot system
run 'mux ifc' in u-boot to validate IFC with invalidating SDHC.

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.
