Since the algorithm rely on the fact that accessing to not existent
memory lead to write at addr / 2 without this modification accesses to
aliased (not physically present) addresses are cached and wrong size is

Fix the write to the HPRT register which treat W1C fields
as if they were mere RW. This leads to unintended clearing of such fields
This bug was found during the testing on Simics model. Referring to
specification DesignWare Cores USB 2.0 Hi-Speed On-The-Go (OTG)
Databook (3.30a)"5.3.4.8 Host Port Control and Status Register (HPRT)", the
HPRT.PrtPwr is cleared by this mistake. In the Linux driver (contrary to
U-Boot), HPRT is always read using dwc2_read_hprt0 helper function which
clears W1C bits. So after write back those bits are zeroes.

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).

dm_test_restore() is called after dm unit test is run.
But this function does not scan any nodes under /firmware since
it calls dm_scan_fdt().
This causes an issue. For instance, scmi_sandbox_agent device
will disappear after running 'ut dm scmi_sandbox_agent'.
So call dm_extended_scan() instead. This change will be coherent
with what dm_scan() and test_pre_run() does.

- move nvmxip header to include
- setup fwu metadata structures as packed (we have a 32bit
writer - Secure enclave Cortex-M0 and a 64bit reader host
Cortex-A35)
Enable the newest features: nvmxip, fwu-metadata and
gpt. Commands to print the partition info, gpt info
and fwu metadata will be available.
Adjust also env boot script the address of the
