arch/mach-meson has some custom usb logic, in particular:
* on board_usb_init(), we force USB_DR_MODE_PERIPHERAL
* on board_usb_cleanup(), we force USB_DR_MODE_HOST
With DM_USB_GADGET=y, board_usb_init/cleanup() are no
longer used when we call usb_gadget_initialize().
Instead, the generic (from udc-uclass) initialization/release is
called, which itself calls the controller driver's probe()/remove().
Therefore, enabling DM_USB_GADGET=y will mean that this mode
switching will break.
To prepare for enabling DM_USB_GADGET, perform the mode switching
when the "amlogic,meson-g12a-usb" (dwc2) driver is
probed()/removed() instead.
This is achieved via the glue driver, which gets notified each time one
of its children is probed()/removed.
Note: this change should be harmless without DM_USB_GADGET=y
because the amlogic-g12a-usb driver is not probed via driver model.

As discussed previously [1,2], the source command is not safe to use with
verified boot unless there is a key with required = "images" (which has its
own problems). This is because if such a key is absent, signatures are
verified but not required. It is assumed that configuration nodes will
provide the signature. Because the source command does not use
configurations to determine the image to source, effectively no
verification takes place.
To address this, allow specifying configuration nodes. We use the same
syntax as the bootm command (helpfully provided for us by fit_parse_conf).
By default, we first try the default config and then the default image. To
force using a config, # must be present in the command (e.g. `source
$loadaddr#my-conf`). For convenience, the config may be omitted, just like
the address may be (e.g. `source \#`). This also works for images
(`source :` behaves exactly like `source` currently does).

Two callers of image_source_script specify an image name. However, both
use the deprecated @ syntax, indicating that they have not been updated
in a while. If CONFIG_FIT_SIGNATURE is enabled, we will reject such
names outright. Back in commit 152576a598 ("stm32mp: stm32prog: handle

nodes. Instead of hard-coding a script image name, just use the default

GUCTL.REFCLKPER can only account for clock frequencies with integer
periods. To address this, program REFCLK_FLADJ with the relative error
caused by period truncation. The formula given in the register reference
has been rearranged to allow calculation based on rate (instead of
period), and to allow for fixed-point arithmetic.
Additionally, calculate a value for 240MHZDECR. This configures a
simulated 240Mhz clock using a counter with one fractional bit (PLS1).
This register is programmed only for versions >= 2.50a, since this is
the check also used by commit db2be4e9e30c ("usb: dwc3: Add frame length
adjustment quirk").

When host issues "fastboot reboot fastboot", it's expected that the
board drops the USB connection before resetting.
On some boards, such as Khadas VIM3L and SEI610, this is not the case.
We observe the following error:
$ fastboot reboot fastboot
Rebooting into fastboot OKAY [ 0.004s]
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
This does not happen when we use the RST button on the board.
It can be reproduced in linux with:
# echo b > /proc/sysrq-trigger
In this case, we hit a undefined hardware behavior, where D+ and D-
are in an unknown state. Therefore the host can't detect usb
disconnection.
Make sure we always call usb_gadget_release() when a "fastboot reboot"
command is issued.
Note: usb_gadget_release() should be called before g_dnl_unregister()
because g_dnl_unregister() triggers a complete() call on each
endpoint (thus calling do_reset()).
