1. Fix the issue that Wi-Fi can't connect to some special routers occasionally.
2. Update Wi-Fi driver code to fix issue of failure to send pkt.
3. Replace software random with hardware random
since all NX and VNC initialization should be initiated from
user space through BOARDIOC_NX_START and BOARDIOC_VNC_START

commit 2889315c20 added support for pwm
but didn't read the channel numbers provided by user-space. They should
be, otherwise it's not possible to start a sub-set of channels that are
not the first "n" channels.
commit 3b69d09c80 corrected the
unreachable handling for net/udp/icmp but introduced an unaligned store.
This splits the uint32_t data field into a two element uint16_t data
field to avoid the unaligned store.
commit 7354ab187e added an option to break
the loops when using multiple PWM channels to arm pwm drivers. This adds
the same support to the risc-v pwm drivers.
Wrong unackseq calculation locked conn->tx_unacked at non-zero values
even if all ACKs were received. Thus unbuffered psock_tcp_send() never completed.

If the remote TCP receiver advertised TCP window size greater than 64 KB
and TCP ACK packets returned to the NuttX TCP sender with a significant delay,
tx_unacked variable overflowed and further TCP send stalled forever
(until TCP re-connection).
Update the cache settings for the Aries m100pfsevp board. This
assigns scratchpad ways for this board as well, as seen in the
commit 491ae6c.

The source directory contents of the OpenSBI directory lib/sbi may be
listed with a one-line wildcard. This makes the Make.defs file look
simpler. The rest of the files need to be picked one at a time.

OpenSBI may be compiled as an external library. OpenSBI commit d249d65
(Dec. 11, 2021) needs to be reverted as it causes memcpy / memcmp to
end up in the wrong section. That issue has yet no known workaround.
OpenSBI may be lauched from the hart0 (e51). It will start the U-Boot
and eventually the Linux kernel on harts 1-4.
OpenSBI, once initialized properly, will trap and handle illegal
instructions (for example, CSR time) and unaligned address accesses
among other things.
Due to size size limitations for the mpfs eNVM area where the NuttX
is located, we actually set up the OpenSBI on its own section which
is in the bottom of the DDR memory. Special care must be taken so that
the kernel doesn't override the OpenSBI. For example, the Linux device
tree may reserve some space from the beginning:
opensbi_reserved: opensbi@80000000 {
reg = <0x80000000 0x200000>;
label = "opensbi-reserved";
};
The resulting nuttx.bin file is very large, but objcopy is used to
create the final binary images for the regions (eNVM and DDR) using
the nuttx elf file.

Assign ways to L2 zerodevice. L2 zero device is used for
the scratchpad functionality. The area may be used for the
harts communicating to each other.
