Currently we only read the pcr updates once on test_tpm2_pcr_read().
It turns out that the tpm init sequence of force_init() which consists
of:
- tpm2 init
- tpm2 startup TPM2_SU_CLEAR
- tpm2 self_test full
- tpm2 clear TPM2_RH_LOCKOUT
also counts as an update. Running this in the console verifies the
update bump

With the recent changes of replacing 'tpm2 init' with 'tpm2 autostart'
we end up always running the full init. The reason is 'tpm init'
returns -EBUSY if the tpm is already open, while 'tpm autostart' handles
ths gracefully and continues with the initialization. It's worth noting
that this won't affect the device functionality at all since
retriggering the startup sequence and selftests has no side effects.
Instead of relying on the initial value, reread the 'known updates'
just before updating the PCR to ensure we read the correct values
before testing

Instead of copy pasting the commands needed to start a TPM consisting
of:
- tpm init
- tpm startup TPM2_SU_CLEAR
- tpm2 self_test full
use the newly added 'autostart' which does the same thing and simplify

For a TPM device to be operational we need to initialize it and
perform its startup sequence. The 'tpm init' command currently calls
tpm_init() which ends up calling the ->open() per-device callback and
performs the initial hardware configuration as well as requesting
locality 0 for the caller. There no code that currently calls
tpm_init() without following up with a tpm_startup() and tpm_self_test_full()
or tpm_continue_self_test().
So let's add a 'tpm autostart' command and call tpm_auto_start() which
leaves the device in an operational state.
It's worth noting that calling tpm_init() only, doesn't allow a someone
to use the TPM since the startup sequence is mandatory. We always
repeat the pattern of calling
- tpm_init()
- tpm_startup()
- tpm_self_test_full() or tpm_continue_self_test()

The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort
Subsystem. It includes a buffer manager, blender, an audio mixer and a
DisplayPort source controller (transmitter). The DisplayPort controller can
source data from memory (non-live input) or the stream (live input). The
DisplayPort controller is responsible for managing the link and physical
layer functionality. The controller packs audio/video data into transfer
units and sends them over the main link. The link rate and lane counts can
be selected based on the application bandwidth requirements. The
DisplayPort pipeline consists of the DisplayPort direct memory access (DMA)
for fetching data from memory. The DisplayPort DMA controller (DPDMA)
supports up to six input channels as non-live input.
This driver supports the DisplayPort Subsystem and implements
1)640x480 resolution
2)RGBA8888 32bpp format
3)DPDMA channel 3 for Graphics
4)Non-live input
5)Fixed 5.4G link rate
6)Tested on ZCU102 board
There will be additional work to configure GT lines based on DT, higher
resolutions, support for more compressed video formats, spliting code to
more files, add support for EDID, audio support, using clock framework for
all clocks and in general code clean up.

So print 'ERROR: Invalid size 0' and return cmd failure when length '0' is
passed to sf commands. Same thing applies for nand commands also.
Example:
ZynqMP> sf erase 0 0
ERROR: Invalid size 0
ZynqMP> sf write 10000 0 0
ERROR: Invalid size 0
ZynqMP> sf read 10000 0 0

U-Boot writes to RX packets when constructing replies.
This can cause stale cached data to be written to RX
buffer while we're receiving a packet. This causes RX
packet corruption because we invalidate the cache right
before processing the packet. Invalidate packet buffer
cache when preparing RX descriptor as well. This seems
to fix RX packet drops with high RX traffic.
While at it flush the descriptors right before enabling
RX/TX in sh_eth_tx_desc_init/sh_eth_rx_desc_init callbacks
when they are ready instead of flushing after allocation.
