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()).

In general handles should only be deleted if the last remaining protocol
is removed. Instead of explicitly calling
efi_create_handle -> efi_add_protocol -> efi_delete_handle which blindly
removes all protocols from a handle before removing it, use
InstallMultiple/UninstallMultiple which adheres to the EFI spec and only
deletes a handle if there are no additional protocols present

is associated with the handle.

The fdt command currently handles stringlists as strings in 'fdt get value'
subcommand. Since strings in FDT stringlists are separated by '\0', only
the first value gets inserted into the environment variable passed to the
'fdt get value' command.
Example, consider the following DT snippet:
/ { compatible = "foo", "bar" };
The following command only reports the first string in stringlist:
=> fdt get value var / compatible ; print var
foo
It is not possible to assign list of null-terminated strings into U-Boot
environment variable. Add optional 'index' parameter to the subcommand
'fdt get value <var> <path> <prop> [<index>]' which lets user specify which
string within the stringlist should be assigned into the 'var' variable.
The default value of 'index' is 0 in case it is not present. This way the
'fdt' command API does not change and existing scripts are not broken.
The following command now reports the Nth string in stringlist, counting
from zero:
=> fdt get value var / compatible 1 ; print var
bar

UEFI specification requires booting from removal media using
a architecture-specific default image name such as BOOTAA64.EFI.
This commit adds the removable media entries into bootmenu,
so that user can select the removable media and boot with
default image.
The bootmenu automatically enumerates the possible bootable
media devices supporting EFI_SIMPLE_FILE_SYSTEM_PROTOCOL,
add it as new UEFI boot option(BOOT####) and update BootOrder
variable. This automatically generated UEFI boot option
has the dedicated guid in the optional_data to distinguish it from
the UEFI boot option user adds manually. This optional_data is
removed when the efi bootmgr loads the selected UEFI boot option.
This commit also provides the BOOT#### variable maintenance feature.
Depending on the system hardware setup, some devices
may not exist at a later system boot, so bootmenu checks the
available device in each bootmenu invocation and automatically
removes the BOOT#### variable corrensponding to the non-existent
media device.

This patch adds the cyclic command, which currently only supports the
'list' subcommand, to list all currently registered cyclic functions.
Here an example:
=> cyclic list
function: cyclic_demo, cpu-time: 7010 us, frequency: 99.80 times/s
function: cyclic_demo2, cpu-time: 1 us, frequency: 1.13 times/s
As you can see, the cpu-time is accounted, so that cyclic functions
that take too long might be discovered. Additionally the frequency is
logged.
The 'cyclic demo' commands registers the cyclic_demo() function to
be executed all 'cycletime_ms' milliseconds. The only thing this
function does is delaying by 'delay_us' microseconds.

For obvious reasons BootROMS rejects unsigned images when secure boot is

U-Boot fuse API is currently implemented only for A38x and A37xx SoCs.
Additionally Armada 3700 BootROM rejects signed trusted image when secure
boot is not enabled in OTP. So add also check for this case. On the other
hand Armada 38x BootROM acceps images with secure boot header when secure
boot is not enabled in OTP.
OTP secure bits may have burned also boot device source. Check it also and
reject flashing images to target storage which does not match OTP.

The commit is largely wrong and breaks most of i2c command functionality.
The problem described in the aforementioned commit commit message is valid,
however the commit itself does many more changes unrelated to fixing that
one problem it describes. Those extra changes, namely the handling of i2c
device address length as unsigned instead of signed integer, breaks the
expectation that address length may be negative value. The negative value
is used by DM to indicate that address length of device does not change.
The actual bug documented in commit 8f8c04bf1e
