The RPMB partition cannot be accessed via standard block layer, but by a set of specific commands: WRITE, READ, GET_WRITE_COUNTER, and PROGRAM_KEY. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage.

In sensor_rpmsg_ioctl, when rpmsg_get_tx_payload_buffer is block,
The rptun thread will continue to process rx_buffers from other cores,
So the proxy may be released in sensor_unadv_handler, then if using
the proxy, It causes a crash.

This change fixes the issue when SAMv7 GMAC sometimes does not start packet
transmission. The issue is that EMAC_NCR_TSTART is written to EMAC_NCR register
while tx descriptor is not delivered to memory.

Some SD card connectors do not have separate card detection pin. In that
case card detection has to be done on CD/DAT3 data line. This means
software (i.e. architecture level driver) has to take care of pin
configuration switching (pin has to be set as data pin in case of
transfer and as interrupt card detection pin when there is no action
on data line).
This commit adds CD/DAT3 line card detection support for SAMv7 MCU.

Workaround to avoid deadlock situation: The RX shall not try to wait for complete
frame in case there is RX errors detected.
In case mpfs_receive is called, it keeps waiting for complete frame and
also keeps the net_lock locked. In the mean while, the TX may run out of free
descriptors, but can not get net_lock mutex lock to be able to release used
descriptors. If there are no free TX descs it disables RX interrupts because
it may require to send response to the received frame.
So, TX side keeps RX interrupts disabled due to lack of free descriptors and
RX blocks TX to release those descs by stubbornly waiting for complete frame.
When the system starts up, the hw count may not start counting from 0,
which can cause the processing time of the first oneshot handler to be
too long. Therefore, the current tick value should be set based on the
hw count during initialization.

RPMSG is associated with the use of HPWORK / LPWORK queues.
After sending a message to the remote end (Linux), the system
waits for an ack before proceeding. Unfortunately this may
take sometimes more time than one would expect. Ack waiting is
also unnecessary: nothing is done with that information. Even
worse, the net_lock() is also held during the blocked time so
it blocks other network stacks that are unrelated to this.
Also reorganize the mpfs_opensbi_*.S so that the trap
handler is easily relocated in the linker .ld file without
the need to relocate the utils.S. This makes it easier to
separate the files into own segments. The trap file should be
located in the zero device.
Moreover, provide support for simultaneous ACK and message
present handling capabilities in both directions. There are
times when both bits are set but only other is being handled.
In the end, the maximum throughput of the RPMSG bus increases
easily 10-20% or even more.
