Provide armffa command showcasing the use of the U-Boot FF-A support
armffa is a command showcasing how to invoke FF-A operations.
This provides a guidance to the client developers on how to
call the FF-A bus interfaces. The command also allows to gather secure
partitions information and ping these partitions. The command is also
helpful in testing the communication with secure partitions.
For more details please refer to the command documentation [1].

It is is sometimes desired to be able to skip decrementing the number of
tries remaining in an Android A/B boot, and instead just check which
slot will be tried later. This can commonly be be the case for platforms
that want to A/B u-boot itself, but are required to boot from a FAT MBR
partition. In these cases, u-boot must do an early check that the MBR
points to the correct A/B boot partition, and if not rewrite the MBR to
point to the correct one and reboot. Decrementing the try count in this
case is not desired because it means that each u-boot might constantly
ping-pong overwriting the MBR and rebooting until all the retries are
used up.

Commands causing reset in some configs:
When bootflow scan is run, this will cause a UCLASS_BOOTDEV device to
be added as sibling of those UCLASS_BLK devices found in the search
chain defined in environment variable "boot_targets", until boot
succeeds from some device. This can happen automatically as part of
the default boot process on some boards (example: Rock Pi 4) depending
on the board configuration (DISTRO_DEFAULTS, BOOTSTD, BOOTCOMMAND,
etc.) because they have bootcmd=bootflow scan.
If boot doesn't succeed from any device, and usb is in boot_targets,
and an usb storage device is plugged to some usb port at boot time,
its UCLASS_MASS_STORAGE device will have a UCLASS_BOOTDEV device as
child, besides a UCLASS_BLK child.
If once the boot fails the user enters at the U-Boot shell prompt:
usb info
or
usb tree
The code in cmd/usb.c will eventually recurse into the UCLASS_BOOTDEV
device and pass a null usb_device pointer to usb_show_tree_graph() or
usb_show_info() (because it has no parent_priv_).
This causes a reset. The expected behaviour would be to ignore the
UCLASS_BOOTDEV device, continue listing the usb information and return
to the prompt.
Minimal test:
Another way to trigger this reset as a minimal test or on boards with
a different bootcmd would be:
- make sure "usb" is in environment variable boot_targets (might need
setenv boot_targets usb; and/or saveenv and reset), then, with a usb
storage device plugged to a usb port, run:
=> usb reset ; bootflow scan ; usb info
Solution:
Fix it (twice) by checking for null parent_priv_ and adding
UCLASS_BOOTDEV to the list of ignored class ids before the recursive
call.
This prevents the current particular problem with UCLASS_BOOTDEV, even
in case it ever gets some parent_priv_ struct which is not an
usb_device, despite being the child of a usb_device->dev. And it also
prevents possible future problems if other children are added to usb
devices that don't have parent_priv_ because they are not part of the
usb tree, just abstractions of functionality (like UCLASS_BLK and
UCLASS_BOOTDEV are now).

For a TPM device to be operational we need to initialize it and
perform its startup sequence. The 'tpm init' command currently calls
tpm_init() which ends up calling the ->open() per-device callback and
performs the initial hardware configuration as well as requesting
locality 0 for the caller. There no code that currently calls
tpm_init() without following up with a tpm_startup() and tpm_self_test_full()
or tpm_continue_self_test().
So let's add a 'tpm autostart' command and call tpm_auto_start() which
leaves the device in an operational state.
It's worth noting that calling tpm_init() only, doesn't allow a someone
to use the TPM since the startup sequence is mandatory. We always
repeat the pattern of calling
- tpm_init()
- tpm_startup()
- tpm_self_test_full() or tpm_continue_self_test()
