f1683aa73c board_f: Rename initdram() to dram_init()
This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

088454cde2 board_f: Drop return value from initdram()
At present we cannot use this function as an init sequence call without a
wrapper, since it returns the RAM size. Adjust it to set the RAM size in
global_data instead, and return 0 on success.

52c411805c board_f: Drop board_type parameter from initdram()
It looks like only cm5200 and tqm8xx use this feature, so we don't really
need it in generic code. Drop it and have the users access gd->board_type
directly.

7ffe3cd62e Delete tests of CONFIG_OF_LIBFDT when testing CONFIG_OF_BOARD_SETUP
Since CONFIG_OF_BOARD_SETUP depends on CONFIG_OF_LIBFDT:

  config OF_BOARD_SETUP
          bool "Set up board-specific details in device tree before boot"
          depends on OF_LIBFDT
          ...

remove superfluous tests of CONFIG_OF_LIBFDT when testing for
CONFIG_OF_BOARD_SETUP.

e895a4b06f fdt: Allow ft_board_setup() to report failure
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.

0092fa01a7 a3m071: Make spl_start_uboot test like getenv_yesno does
This change makes the behaviour slightly more rebust and will match
other implementations which can use getenv_yesno directly.

aed7548448 mpc5200: a4m2k: Implement custom "dynamic" watchdog support
This patch adds a custom U-Boot command "wdogtoggle" which enables the
external hardware watchdog toggling via an GPIO pin on the a4m2k
board. After issuing this commands, the watchdog will be serviced
by U-Boot so that the user can use all U-Boot commands from the
prompt.

d4451d3503 mpc5200: Add a4m2k board port
This patch adds the a4m2k MPC5200B board port. Its a derivate of
the a3m071 board with only minor changes.

Additionally this patch includes some clean-up changes:
- Remove I2C support from a3m071 as its unused
- Fix/enhance default env variables
- Fix some comments
- Add newly introduced CONFIG_SPL_TARGET to automatically build
  "u-boot-img.bin"
- Fix dtb patching in READ desciption for SPL Linux booting:
  "fdt chosen" needs to get called to patch/create the chosen node.
- Add missing call to spl_board_init():
  Define CONFIG_SPL_BOARD_INIT so that spl_board_init() will get
  called in the SPL version.
