If there's a disconnection while operating in eSS, there may be a delay
in VBUS drop response from the connector. In that case, the internal
link state may drop to operate in usb2 speed while the controller thinks
the VBUS is still high. The driver must make sure to disable
GUSB2PHYCFG.SUSPHY when sending endpoint command while in usb2 speed.
The End Transfer command may be called, and only that command needs to
go through at this point. Let's keep it simple and unconditionally
disable GUSB2PHYCFG.SUSPHY whenever we issue the command.
This scenario is not seen in real hardware. In a rare case, our
prototype type-c controller/interface may have a slow response
triggerring this issue.
The cmd argument we pass to
dwc3_send_gadget_ep_cmd() could contain extra
arguments embedded. When checking for StartTransfer
command, we need to make sure to match only lower 4
bits which contain the actual command and ignore the
rest.

dma: ti: k3-udma: invalidate prepared buffers before pushing to recv ring
Buffers must not have an unclean cache before being used for DMA - a
pending write-back may corrupt the next dev-to-mem transfer otherwise.
This was consistently noticeable during long TFTP transfers, when an ARP
request is answered by U-Boot in the middle of the transfer:
As U-Boot's arp_receive() reuses the receive buffer to prepare its
reply packet, the beginning of one of the next incoming TFTP packets
is overwritten by the ARP reply. The corrupted packet is ignored, but
the TFTP transfer stalls for a few seconds until a timeout is detected
and a retransmit is triggered.

net: ti: am65-cpsw-nuss: avoid errors due to imbalanced start()/stop()
The eth-uclass state machine doesn't prevent imbalanced start()/stop()
calls - to the contrary, it even provides eth_init_state_only() and
eth_halt_state_only() functions that change the state without any calls
into the driver. This means that the driver must be robust against
duplicate start() and stop() calls as well as send/recv calls while the
interface is down.
We decide not to print error messages but just to return an error in the
latter case, as trying to send packets on a disabled interface commonly
happens when the netconsole is still active after the Ethernet has been
halted during bootm.

If running at EL2 or above (where CNTHCTL_EL2 is available), enable

core drivers that are required for being able to boot any board--a UART
driver, the gptimer driver which is used as a clock reference (CNTVCNT
is not supported on the armv7 sc5xx SoCs) and the clock tree driver. Our
corresponding Linux support relies on u-boot configuring the clocks
correctly before booting, so it is not possible to boot any board
without the CGU/CDU configuration happening here. There are also no
board files, device trees, or defconfigs included here, but some common
definitions that will be used to build board files currently are. The
sc5xx SoCs themselves include many armv7 families (sc57x, sc58x, and
sc594) all using an ARM Cortex-A5, and one armv8 family (sc598) indended
to be a drop-in replacement for the SC594 in terms of peripherals, with
a Cortex-A55 instead.
Some of the configuration code in dmcinit and clkinit is quite scary and
causes a lot of checkpatch violations. It is modified from code
initially provided by ADI, but it has not been fully rewritten. There's
a question of how important it is to clean up this code--it has some
quality violations, but it has been in use (including in production) for
over two years and is known to work for performing the low level SoC
initialization, while a rewrite might introduce timing or sequence bugs
that could take a significant amount of time to detect in the future.
