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.

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.

Martyn Welch <martyn.welch@collabora.com> says:
This series adds DFU support for TI AM62 SK and beagleplay boards.
I have picked this series up from Sjoerd due to time constraints.
Since the last revision:
* Removed dwc3 mode setting in favour of reinstating forced peripheral
mode for usb0
* Use of config fragments for both r5 and a53 DFU configuration to
reduce duplication
* Typographical improvements to documentation
We plan to also submit the dts changes to linux so that those can be
dropped again in the near future (hopefully)
DFU mode on a beagleplay can be used via the Type-C connector by holding
the USR switch while powering on.
Configuration is already provided as fragments for both the A53 and R5
u-boot parts. Include the am62x_a53_usbdfu.config config. The
am62x_r5_usbdfu.config fragment needs to be added should DFU boot be
required as this will disable booting from persistent storage due to
binary size constraints.

Provide config fragments to enable USB host as well as USB gadget and DFU
support for a53 and r5. This relevant fragment is included into the
am62x EVM a53 defconfig. For the r5, due to the smaller available size,
the config fragment also disables support for persistent storage to free
up space for USB support. This fragment needs to be included is DFU
booting is desired.
The CONFIG_DFU_SF option is placed in the defconfig rather than the
fragment as this is known not to be supported on all boards that can
support DFU.

* We already have a header 'backtrace', there is no need to repeat the
word backtrace on every line.
* Add a blank line before the backtrace section of the crash report for
improved readability.
* If U-Boot is compiled without backtrace, there is no need to write a
message at all.
* Avoid #ifdef. We prefer functions to always be compiled and let
the linker remove them if not needed.
* Foresee 3 digits for the backtrace index.

When the device port is in a low power state [U3/L2/Not Connected],
accesses to usb device registers may take a long time. This could lead to
potential core hang when the controller registers are accessed after the
port is disabled by setting DEVDS field. Setting the fast register access
bit ensures that the PHY clock is keeping up in active state.
Therefore, set fast access bit to ensure the accesses to device registers
are quick even in low power states.

upstream kernel is taken as reference.

The newly introduced carve_out_reserved_memory causes issues when
U-Boot is chained from the lk2nd bootloader. lk2nd provides a
simple-framebuffer device and marks the framebuffer region as no-map in
the supplied /reserved-memory. Consequently, the simple_video driver
triggers a page fault when it tries to write to this region.
As per Caleb's advice, this simple patch only does the carveouts for the
qcs404 SoC for which it was originally designed. The intent is to do the
carveouts for more Qualcomm SoCs in future.

Polling cntpct_el0 in a tight loop for delays is inefficient.
This is particularly apparent on Arm FVPs, which do not simulate
real time, meaning that a 1s sleep can take a couple of orders
of magnitude longer to execute in wall time.
If running at EL2 or above (where CNTHCTL_EL2 is available), enable
the cntpct_el0 event stream temporarily and use wfe to implement
the delay more efficiently. The event period is chosen as a
trade-off between efficiency and the fact that Arm FVPs do not
typically simulate real time.
This is only implemented for Armv8 boards, where an architectural
timer exists, and only enabled by default for the ARCH_VEXPRESS64
board family.

wfe may theoretically trigger a context switch if an interrupt occurs
so add a memory barrier to this call.
