usb: bootm: Drop old USB-device-removal code
USB is stopped using driver model now, in dm_remove_devices_flags() in
announce_and_cleanup() at the top of this file.
The usb_stop() call actually unbinds devices.
When a USB device is unbound, it causes any bootflows attached to it to
be removed, via a call to bootdev_clear_bootflows() from
bootdev_pre_unbind(). This obviously makes it impossible to boot the
bootflow.
However, when booting a bootflow that relies on USB, usb_stop() is
called, which unbinds the device. At that point any information
attached to the bootflow is dropped.
This is quite risky since the contents of freed memory are not
guaranteed to remain unchanged. Depending on what other options are
done before boot, a hard-to-find bug may crop up.
Drop the call to this old function.
Leave the netconsole call there, since this needs conversion to
driver model.

tools: Add script to update git subtree projects
Recently we are introducing multiple git subtree projects and
it is the right time to have a universal script to update
various subtrees and replace the dts/update-dts-subtree.sh.
update-subtree.sh is a wrapper of git subtree commands.
Usage: From U-Boot top directory,
run
$ ./tools/update-subtree.sh pull <subtree-name> <release-tag>
for pulling a tag from the upstream.
Or run
$ ./tools/update-subtree.sh pick <subtree-name> <commit-id>
for cherry-pick a commit from the upstream.
Currently <subtree-name> supports dts, mbedtls and lwip.

video: Use cyclic to handle video sync
At present U-Boot flushes the cache after every character written to

binman: fit: Allow running fdtgrep on devicetree blobs
When using FIT to load firmware builds for multiple models, the FIT must
include a common binary along with a number of devicetree blobs, one for
each model. This is the same mechanism as is used for loading an OS.
However, SPL builds do not normally use the full devicetree, but instead
a cut-down version which various nodes and properties removed.
Add a new fit,fdt-phase property to allow binman to produce these
devicetree blobs.

binman: Add support for alternative FDTs
FIT provides a way to select between different devicetree blobs
depending on the model. This works fine for U-Boot proper and allows SPL
to select the correct blob for the current board at runtime. The boot
sequence (SPL->U-Boot proper) is therefore covered by the existing
feature set.
The first boot phase (typically TPL) cannot use FIT since SoC boot ROMs
don't currently support it. Therefore the TPL image must be specific to
each model it boots on.
To support booting on mulitple models, binman must therefore produce a
separate TPL image for each model, even if the images for the rest of
the phases are identical.
TPL needs to be packaged as an executable binary along with a reduced
devicetree. When multiple models are supported, a reduced devicetree
must be provided for each model.
U-Boot's build system is designed to build a single devicetree for SPL
builds, so does not support this requirement.
Add a new 'alternatives' feature to Binman, allowing it to automatically
subset a devicetree to produce the reduced devicetree for a particular
phase for each supported model. With this it is possible to produce a
separate TPL image for each of the models. The correct one can then be
loaded onto a board, along with the common FIT image(s).
