The 'blks' variable in scsi_read/write/erase functions is updated
regardless of pass/fail of the scsi operation . If the scsi operation
fails, 'blkcnt' is updated using an incorrect value of 'blks'. This
wrong 'blkcnt' is returned to the caller and it assumes all blocks were
processed correctly.
Fix this by updating the 'blks' variable only if the scsi operation
succeeds.

The Auto Negotiation procedure between two Ethernet PHYs consists of
determining the best commonly supported parameters among Speed,
Duplex Mode and Flow Control.
The time taken for this procedure is not only dependent on the local
PHY used, but also on the link-partner PHY.
While a timeout can be specified in the form of a "CONFIG" on the basis
of the local PHY present on the device, since the timeout also depends
on the link-partner PHY, it might be necessary to modify the timeout.
To avoid rebuilding the bootloader for a given device, just because it
may be connected to various link-partner PHYs, each with a different
timeout, introduce an environment variable named "phy_aneg_timeout" and
override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

This driver allows using Tegra AES engines within BSEV and BSEA blocks to
encrypt and decrypt data using different AES algorithms.
One use case is allowing u-boot to self update by using the already loaded
AES key in the engine's SBK slot by the bootrom.
Particular care must be taken as chainloaded u-boot's may not have the SBK
slot loaded as the vendor bootloader erases it before leaving it.

This patch set has been tested on Agilex 5 devkit.
Lukasz Czechowski <lukasz.czechowski@thaumatec.com> says:
This patch series extends the usb_onboard_hub driver to allow for
support of more types of onboard hub devices, and adds the Cypress HX3
hub family.
First patch in the series updates the bind function, so that it no
longer uses hardcoded compatible strings.
Next patch simplifies the code, by removing unnecessary dm_gpio function
call.
Third patch updates the remove function, which allows the prevent issues
with usb devices reenumeration, in case of calling "usb reset". Although
the issue could still occur in case of invalid initial state of reset
gpio, it is minimized with no impact on main usb_hub driver.
Fourth patch extends the driver with support for multiple power
supplies, the same way it is done in kernel driver. Finally, last patch
provides hub data and of_match table entries for Cypress HX3

The reset GPIO is obtained during driver probing by the function
devm_gpiod_get_optional, which means the GPIO will be automatically
freed when the device is removed. Because of this, explicit call
to free the reset GPIO in hub remove function is not needed.
To support the Managed device resources, the DEVRES config must
be enabled, otherwise the devres functions fall back to non-managed
variants. Set the necessary dependency to DEVRES in Kconfig.
