By default several types of splash locations are supported and the
user can select one of them through environment var (splashsource).
However the devpart is still hardcoded and we cannot change it from
the environment.
This patch add the support of "splashdevpart" which allow the user to
set the devpart though this environment variable.
Example: image located in splashscreen partition (MMC as raw)
```
splashsource=mmc_raw
splashdevpart=0#splashscreen
```

OMAP3 BeagleBoard NAND boot hangs when spl_load_legacy_img() tries
to read the header into 'struct hdr' which is allocated on the
stack.
As the header has already been read once before by spl_nand.c,
we can avoid the extra header allocation and read here by
simply passing around the pointer to the header.
This fixes NAND boot on OMAP3 BeagleBoard.

With the migration of the watchdog infrastructure to cyclic functions
it's been noticed, that at least one watchdog driver is broken now. As
the execution time of it's watchdog reset function is quite long.
In general it's not really necessary (right now) to disable the cyclic
function upon exceeding CPU time usage. So instead of disabling the
cylic function in this case, let's just print a warning once to show

Beside some rather unexciting sync of the DTs from the kernel tree, and
some Kconfig cleanup, there are some improvements for the ARMv5 Allwinner
family, to support boards with the F1C200s (64MB DRAM) better. We will
get actual board support as soon as the DTs have passed the Linux review
process.
There is also support for the X96 Mate TV Box, featuring the H616 SoC and
a full 4GB of DRAM.
Also we found the secret to enable SPI booting on the H616 (pin PC5 must
be pulled to GND), so the SPI boot support patch is now good to go.
Passed the gitlab CI, plus briefly tested on Pine64-LTS, LicheePi Nano,
X96 Mate and OrangePi Zero.
Some configuration symbols formerly defined in header files were
recently converted to Kconfig symbols. This moved their value definition
into *every* defconfig file, even though those values are hardly board
choices.
Use the new Kconfig option to define per-SoC default values, in just one
place, which makes the definition in each defconfig file redundant.
We refrain from setting a sunxi specific value for CONFIG_SYS_BOOTM_LEN,
so this defaults to a much better 64MB for uncompressed arm64 kernels.

Currently, AUTOBOOT_KEYED and its variant AUTOBOOT_ENCRYPTION are
broken when one has an external always-running watchdog device with a
timeout shorter than the configured boot delay (in my case, I have a
gpio-wdt one with a timeout of 1 second), because we fail to call
WATCHDOG_RESET() in the loops where we wait for the bootdelay to
elapse.
This is done implicitly in the !AUTOBOOT_KEYED case,
i.e. abortboot_single_key(), because that loop contains a
udelay(10000), and udelay() does a WATCHDOG_RESET().
To fix this, simply add similar udelay() calls in the other loops.

On certain places it is required to flush output print buffers to ensure
that text strings were sent to console or serial devices. For example when
printing message that U-Boot is going to boot kernel or when U-Boot is
going to change baudrate of terminal device.
Therefore introduce a new flush() and fflush() functions into console code.
These functions will call .flush callback of associated stdio_dev device.
As this function may increase U-Boot side, allow to compile U-Boot without
this function. For this purpose there is a new config CONSOLE_FLUSH_SUPPORT
which is enabled by default and can be disabled. It is a good idea to have
this option enabled for all boards which have enough space for it.
When option is disabled when U-Boot defines just empty static inline
function fflush() to avoid ifdefs in other code.

32-bit U-Boot builds cannot use more than around 2 GB of DDR memory. But on
some platforms/boards it is possible to connect also 4 GB SODIMM DDR memory.
U-Boot currently prints only effective size of RAM which can use, which may
be misleading as somebody would expect that this line prints total size of
connected DDR modules. So change show_dram_config code to prints both real
and effective DRAM size if they are different. If they are same then print
just one number like before. It is possible that effective size is just few
bytes smaller than the real size, so print both numbers only in case
function print_size() prints formats them differently.
