This implements a stack usage check in SPL.
Many boards start up SPL to run code + data from one common, rather small
SRAM. To implement a sophisticated SPL binary size limit on such boards,
the stack size (as well as malloc size and global data size) must be
subtracted from this SRAM size.
However, to do that properly, the stack size first needs to be known.
This patch adds a new Kconfig option:
- SPL_SYS_REPORT_STACK_F_USAGE: memset(0xaa) the whole area of the stack
very early and check stack usage based on this constant later before the
stack is switched to DRAM
Initializing the stack and checking it is implemented in weak functions,
in case a board does not use the stack as saved in gd->start_addr_sp.

The current U-Boot SPL image loader infrastructure is very powerful,
able to initialize and load from a variety of boot media however it
is strongly geared towards loading specific types of images in a very
specific way. To address the need being able to use this infrastructure
to load arbitrary image files go ahead and refactor it as follows:
- Refactor existing spl_mmc_load_image function into superset function,
accepting additional arguments such as filenames and media load offset
(same concept can also be applied toother spl_XXX_load_image functions)
- Extend the loader function to "remember" their peripheral initialization
status so that the init is only done once during the boot process,
- Extend the FIT image loading function to allow skipping the parsing/
processing of the FIT contents (so that this can be done separately
in a more customized fashion)
- Populate the SPL_LOAD_IMAGE_METHOD() list with a trampoline function,
invoking the newly refactored superset functions in a way to maintain
compatibility with the existing behavior
This refactoring initially covers MMC/SD card loading (RAW and FS-based).

On some platform we have sufficient memory available early on to allow
setting up and using a basic BSS prior to entering board_init_f(). Doing
so can for example be used to carry state over to board_init_r() without
having to resort to extending U-Boot's global data structure.
To support such scenarios add a Kconfig option called CONFIG_SPL_EARLY_BSS
to allow moving the initialization of BSS prior to entering board_init_f(),
if enabled. Note that using this option usually should go along with using
CONFIG_SPL_SEPARATE_BSS and configuring BSS to be located in memory
actually available prior to board_init_f().

The choice of the SPL_TEXT_BASE is not really a decision that should be
specified by each board's defconfig, as this setting is actually
dictated by the SoC's memory map and the BootROM behaviour.
To make this obvious and reduce the clutter in the defconfig files,
let's specify the SoC constraints in the Kconfig stanza.
This allows us to remove these lines from the defconfig files again.

The motivation is to use the UBI atomic volume rename functionality to
allow double copy software updates on UBI. To that end the SPL is
configured to always load the same volume name (e.g. "u-boot"),
whereas a software updater always installs into the secondary volume
"u-boot_r". After successful installation, these two volume names are
switched.
This extension is protected by #ifdefs as it will somewhat slow down
loading of volumes by id. This is because the code needs to disable
the optimization of ignoring all volume ids which are not
to-be-loaded, since these can only be resolved after attaching.
This adds two vtbl related functions from Linux, which are taken from
the same kernel version as the current main U-Boot UBI code (Linux 4.2
64291f7db5bd8).

By default the configuration of the PMC is to have an external crystal
connected that requires driving on both XIN and XOUT pins.
The bypass configuration means that only XIN will be used, the SoC will not
do any driving, and the XIN needs to be provided with a proper signal.
This is the MOSCXTBY bit in the PMC main clock generator register.
The SPL needs to properly initialize the PMC registers before switching
to external clock signal and raising the clock to the cruise speed.
Also created Kconfig for this specific configuration.
By default this is disabled.

However this does not play well with the SPL_OS_BOOT option that enables
loading different type of next stage firmware, like the OS itself.
When SPL_OS_BOOT is used, do not disable os-tracking. The added footprint
is about 300 Bytes.

This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.
Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.
With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).
This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

In case of DT boot, don't read default speed and mode for SPI from

Remove also use in boards of the value speed=0 (no more supported)

DT values will be always used when available (full DM support of
SPI slave with available DT node) even if speed and mode are requested;

or in SPL boot (in spl_spi_load_image).
