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 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.
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.

When waiting for a response to a sent command, the command
complete bit (MPFS_EMMCSD_SRS12_CC) should always guarantee
the completion of that particular command. There's no need
to have some combinations skipping the check of the command
complete bit. Thus, remove the 'waitbits' parameter as it's
unnecessary.

These functions are strongly declared and thus will be used instead of

Currently configuring the uart3/4 as the serial console
doesn't work. Apply proper changes in mpfs_config.h that
enables the following configuration options:
- CONFIG_UART3_SERIAL_CONSOLE
- CONFIG_UART4_SERIAL_CONSOLE
Also, fix a typo in mpfs_lowputc.c that gives a compile
error if defined.

E51 may configure the L1 and L2 caches. Once configured,
no reconfiguration is possible after hardware reset is
issued.
L2 is 16-way set associative with write-back policy. The
size 2 MB, from which 1 MB is utilized with the values
provided here. That's a total of 8 ways. The rest of the
L2 is left out for the bootloader usage.
mpfs_enable_cache() first checks the bootloader usage
doesn't overlap with the cache itself, thus providing a
set of functional values.

This adds DDR training. The training has a small chance of failing,
and then the training is restarted.
DDR training cannot be done meaningfully while the software is
in DDR. If the system is intended to run from eNVM, like a
bootloader, the linker script should be tuned to utilize the envm
region as follows:
envm (rx) : ORIGIN = 0x20220100, LENGTH = 128K - 256
l2lim (rwx) : ORIGIN = 0x08000000, LENGTH = 1024k
256 bytes are reserved for the system; The fixed block may be
installed from the 'hart-software-services' -repository:
https://github.com/polarfire-soc/hart-software-services.git
For example, the 256-byte image: hss-envm-wrapper-bm1-dummySbic.bin
may be prepended on the nuttx bootloader image in the following
manner:
cat hss-envm-wrapper-bm1-dummySbic.bin > nuttx_bootloader.bin
cat nuttx.bin >> nuttx_bootloader.bin
riscv64-unknown-elf-objcopy -I binary -O ihex --change-section-lma
*+0x20220000 nuttx_bootloader.bin flashable_image.hex
This provides an image 'flashable_image.hex' that may be flashed on
the eNVM region via Microsemi Libero tool.

If we repeatedly call up_cpu_pause and up_cpu_resume, there would be
cases where the next call to up_cpu_pause happens while the other CPU is
still responding to the previous resume request. In this case the
DEBUGASSERT will trigger. We should allow the first CPU to wait until the
other CPU has finished responding to the resume request.

pid variable was initialized to -EINVAL to prevent rt_timer_deinit
from delete an invalid kthread. But priv->pid was being overwritten in the
rt_timer_init, so in case of failure to create a kthread, it would
call rt_timer_deinit with a non expected initialization value.
This adds the emmcsd driver for the Polarfire Icicle kit.
The driver has been tested with several SD-cards, such as:

- Kingston MicroSD Canvas Select Plus
- Sandisk Extreme PRO 32 GB
- Transcend 8 GB MicroSD
