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.

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.

Summary:
- During repeating ostest with sabre-6quad:smp (QEMU),
I noticed that pthread_rwlock_test sometimes stops
- Finally, I found that nxtask_exit() released a critical
section too early before context switching which resulted in
selecting inappropriate TCB
- This commit fixes this issue by moving nxsched_resume_scheduler()
from nxtask_exit() to up_exit() and also removing
spin_setbit() and spin_clrbit() from nxtask_exit()
because the caller holds a critical section
- To be consistent with non-SMP cases, the above changes
were done for all CPU architectures

Summary:
- This commit fixes global IRQ control logic
- In previous implementation, g_cpu_irqset for a remote CPU was
set in sched_add_readytorun(), sched_remove_readytorun() and
up_schedule_sigaction()
- In this implementation, they are removed.
- Instead, in the pause handler, call enter_critical_setion()
which will call up_cpu_paused() then acquire g_cpu_irqlock
- So if a new task with irqcount > 1 restarts on the remote CPU,
the CPU will only hold a critical section. Thus, the issue such as
'POSSIBLE FOR TWO CPUs TO HOLD A CRITICAL SECTION' could be resolved.
- Fix nxsched_resume_scheduler() so that it does not call spin_clrbit()
if a CPU does not hold a g_cpu_irqset
- Fix nxtask_exit() so that it acquires g_cpu_irqlock
- Update TODO
Impact:
- All SMP implementations

- Tested with smp, ostest with the following configurations
- Tested with spresense:wifi_smp (NCPUS=2,4)
- Tested with sabre-6quad:smp (QEMU, dev board)
