EMIF tool for J721E SK is now updated to 0.6.1 that includes
* Updated write DQ training pattern to enable user pattern and clock
pattern (from 0x7 to 0x6).
* Updated IO drive strength to 40-80-80 Ohms.
J721E SK uses the lpddr4 configuration of 4266 MTs data rate which is
the same as J721E EVM but facing random failures. As the tool update is
specific to the SK board, add a new lpddr4 config of 4266 MTs.

S28HS512T on TI SK has sector size of 256KB, so update OSPI partition
to align on 256KB sector size. Since the sector size for MT35XU512ABA
on EVM is 128KB, partitions will remain aligned for EVM.
Also, now since the sector size is 256KB ospi.env.backup will collide
with ospi.sysfw, so move ospi.env.backup to the padding space (0x7C0000)
before ospi.rootfs partition.

There are devices which cause a USB stall when trying to read strings.
Specifically Arduino Mega R3 stalls when trying to read the product
string.
The stall currently remains unhandled, and subsequent retries submit new
transfers on a stopped endpoint which ultimately cause a crash in
abort_td():
WARN halted endpoint, queueing URB anyway.
XHCI control transfer timed out, aborting...

Linux seems to be able to recover from the stall by issuing a
TRB_RESET_EP command.
Introduce reset_ep() which issues a TRB_RESET_EP followed by setting the
transfer ring dequeue pointer via TRB_SET_DEQ. This allows to properly
recover from a USB stall error and continue communicating with the USB
device.

The switch statement in _hw_exception_handler() only covers the
rightmost 5 bits that encode the exception cause:
switch (state & 0x1f)
{

}
For this reason, the "0x1000" case will never be reached, because the 13th
bit was zeroed out. To fix this, move delay slot exception handling before
the switch statement (delay slot (DS) bit in Exception Status Register is
independent of the exception cause (EC)).

CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node
but it uses zynqmp firmware DT node that's why there is a need to bind

Driver itself is simple. It is sending pmufw config object overlay for

In ...domain_on() capabilities are passed and node is requested.

The previous patch is changing U-Boot's behavior wrt certificate based
binary authentication. Specifically an image who's digest of a

The EFI spec allows for images to carry multiple signatures. Currently
we don't adhere to the verification process for such images.
The spec says:
"Multiple signatures are allowed to exist in the binary's certificate
table (as per PE/COFF Section "Attribute Certificate Table"). Only one
hash or signature is required to be present in db in order to pass
validation, so long as neither the SHA-256 hash of the binary nor any
present signature is reflected in dbx."
With our current implementation signing the image with two certificates
and inserting both of them in db and one of them dbx doesn't always reject
the image. The rejection depends on the order that the image was signed
and the order the certificates are read (and checked) in db.
While at it move the sha256 hash verification outside the signature
checking loop, since it only needs to run once per image and get simplify
the logic for authenticating an unsigned imahe using sha256 hashes.

The existing options, "--fit" and "--raw," are only used to put a proper

a capsule. In fact, mkeficapsule does the exact same job in creating
a capsule file whatever the firmware binary type is.
To prepare for the future extension, the command syntax will be a bit
modified to allow users to specify arbitrary GUID for their own FMP driver.
