On the highbank platform the SoC's management controller firmware
will probe the DRAM modules and populates the initial device tree with
the correct values. Therefore the memory sizes in the DT are already
correct, so remove U-Boot's DRAM bank setup so the memory node is not
"fixed up" by u-boot.

The Calxeda highbank SOC needs a custom sequence to bring up SATA links,
so override ahci_link_up with custom function to handle combophy setup.

The Calxeda Midway part has A15 cores, which do not have the Highbank
A9's SCU used there for resetting the chip.
Add code to distinguish between the A9 and the A15 and invoke the
appropriate register writes to support the newer part.

Don't store it in a u32.
Don't dereference the bus address as if it were a virtual address
(fixes 284231e49a ("ahci: Support splitting of read transactions
into multiple chunks")).

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.

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/.
