The objective is to provide a simple way to retrieve a BMP file,
and display it as splashscreen, from extlinux.conf file input.
For this, we take example on https://www.syslinux.org/wiki/
index.php?title=Menu#The_advanced_menu_system
and more particularly on MENU BACKGROUND chapter.
For this, add "menu background" support in pxe command.
As example, extlinux.conf content will look like:
# Generic Distro Configuration file generated by OpenEmbedded

Pull request for UEFI sub-system for v2019.07-rc1 (3)
This patch series reworks the implementation of the `bootefi` command to
remove code duplication by using the LoadImage() boot service to load
binaries.
Missing short texts for UEFI protocols are added for display by the
`efidebug dh` command.
Missing parameter checks for AllocatePages() and CreateDeviceNode() are

When using boot scripts it can become quite hard to understand
which commands are actually executed during bootup (e.g. where
is a kernel image loaded from or which DTB is in use).
Shell scripts suffer from a similar problem and many shells address
this problem with a command execution tracer (e.g. BASH has xtrace,
which can be enabled by "set -x").
This patch introduces a command tracer for U-Boot, which prints
every command with its arguments before it is executed.

This patch update the behavior introduced by
commit 96907c0fe5 ("dm: spi: Read default speed and mode values from DT")
In case of DT boot, don't read default speed and mode for SPI from
CONFIG_* but instead read from DT node. This will make sure that boards
with multiple SPI/QSPI controllers can be probed at different
bus frequencies and SPI modes.
Remove also use in boards of the value speed=0 (no more supported)
for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0.
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;
for example in splash screen support (in splash_sf_read_raw)
or in SPL boot (in spl_spi_load_image).
The caller of spi_get_bus_and_cs() no more need to force speed=0.
But the current behavior don't change if the SPI slave is not
present (device with generic driver is created automatically)
or if platdata is used (CONFIG_OF_PLATDATA).

At present the gpio command only shows GPIOs which are marked as in use.
This makes sense with 'gpio status' since we already have the '-a' flag
to indicate that all GPIOs should be shown. But when a particular GPIO is
requested, it seems better to always display it. At present the request is
simply ignored.
For example if GPIO a10 is not in use, then:
> gpio status a10
shows nothing, not even the function being used for that GPIO. With this
change, it shows the pin status:
> gpio status a10
a10: input: 0 [ ]
Add an extra parameter for this to avoid changing the existing flag
parameter.
