The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also makes this bootloader configuration as default
for esp32c3-generic target and removes the need for running
'make bootloader' command for it.

Ox64 BL808 crashes with a Page Fault when we run `getprime` then `hello`. This is caused by the T-Head C906 MMU incorrectly accessing the MMU Page Tables of the Previous Process (`getprime`) while starting the New Process (`hello`).
To fix the problem, this PR flushes the MMU Cache whenever we point the MMU SATP Register to the New Page Tables. We execute 2 RISC-V Instructions that are specific to T-Head C906:
- DCACHE.IALL: Invalidate all Page Table Entries in the D-Cache
- SYNC.S: Ensure that all Cache Operations are completed
This is derived from the T-Head Errata for Linux Kernel. More details here: https://lupyuen.github.io/articles/mmu#appendix-flush-the-mmu-cache-for-t-head-c906
Modified Files:
- `arch/risc-v/src/common/riscv_mmu.h`: If needed, `mmu_write_satp()` calls `mmu_flush_cache()` (weak function) to flush the MMU Cache. (Like for T-Head C906)
- `arch/risc-v/src/bl808/bl808_mm_init.c`: Flush the MMU Cache for T-Head C906. Extend `mmuflags` from 32-bit to 64-bit to be consistent with `mmu_ln_setentry()`.
- `boards/risc-v/bl808/ox64/configs/nsh/defconfig`: Enable `ostest` in the Build Config. Update `CONFIG_BOARD_LOOPSPERMSEC` according to `calib_udelay`.
Summary:
- I noticed that the hello app crashes due to
https://github.com/apache/nuttx/pull/11576
- This is a tentative fix to avoid the crash
Impact:
- None
Testing:
- Tested with qemu-8.2.0

Previously k230 kernel build needs OpenSBI wrapping for use on
target, thus leading to larger program and memory overheads.
This patch adds alternative small overhead kernel build support.
Changes:
- in arch/risc-v/src/k230:
- k230_head.S entrance renamed for sake of NUTTSBI
- k230_irq.c add M-mode handling for NUTTSBI case
- k230_mm_init.c add L3 table for smaller RAM case
- hardware/k230_plic.h add PLIC_CTRL definition
- Make.defs use CHIP_ASRCS to fix entrance selection
- in boards/risc-v/canmv230/scripts:
- Make.defs add support for NUTTSBI case
Additions:
- in boards/riscv/canmv230/:
- scripts/ld-nuttsbi.script link script for NUTTSBI case
- configs/nsbi/defconfig config for NUTTSBI case
The artifact nuttx.bin from this configuration can be used directly
on target as OpenSBI wrapping is not needed.

Usually the startup script is placed under /etc. The contents of the etc directory
are compiled and linked with Nuttx binary in the form of romfs. After startup,
it will be mounted by Nsh.
etc is generated by the different boards, that use genromfs and xxd tools to generate
and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh
The more common method is etc image generated from the content in the corresponding
board/arch/board/board/src/etc directory, and added by Makefile for example:
boards/sim/sim/sim/src/etc.
But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/
non-privileged mode or the isolated binarys, so as that nsh should use syscall to
access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image
content, because that is generated in board and as a part of Nuttx kernel.
changes:
- move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute.
- move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c
in boards, and no need declaration for romfs_img/romfs_img_len.
This commit changes and updates all configurations in Nuttx arch/board as much as possible,
but if any missing, please refer to the following simple guide:
- rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig
- rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO
- move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need
declaration for romfs_img/romfs_img_len.
- delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c
in board/arch/board/board/src.

changes:
- under boards/risc-v/k230/canmv230/scripts/:
- Make.defs add POSTBUILD actions
- ld-flat.script minor reformating
- ld-kernel.script minor reformating
- under boards/risc-v/k230/canmv230/src/:
- Makefile add clean of generated ROMFS source
- canmv_init.c use `ferr` and drop too late runtime warning
- romfs_stub.c use const for romfs_img_len
The POSTBULD actions can warn stub ROMFS usage at build time, thus
the too late warning in canmv_init.c can be removed.
The cleaning of `libboard.a` in POSTBUILD can also ensure real ROMFS
is in use, as some times weak_data is still in use.

Major changes:
- boards/Kconfig: add new BOARD_K230_CANMV
- arch/risc-v/Kconfig: add new CHIP_K230 chip and ARCH_RV_MMIO_BITS
- arch/risc-v/src/common/riscv_mtimer.c: use ARCH_RV_MMIO_BITS to
select MMIO access width
New additions:
- arch/risc-v/include/k230/: k230 SoC definitions
- arch/risc-v/src/k230/: k230 SoC sources
- boards/risc-v/k230/canmv230/: CanMV-K230 board sources and configs
- Documentation/platforms/risc-v/k230/: simple doc
Note that only FLAT build works for canmv230 now.
This PR has changes in RiscV common layer thus may affect other RiscV ports
It changes the mtime/mtimecmp access control from using config ARCH_RV64 to
newly intorduced config ARCH_RV_MMIO_BITS.
Original design uses ARCH_RV64 to select 64bit MMIO in riscv_mtimer.c, this
can't cope with the situation with K230 --- it has ARCH_RV64 but only can do
32bit MMIO. So a new ARCH_RV_MMIO_BITS config has been introduced. Its value
depicts the MMIO width in bits. The MMIO_BITS defaults to 32/64 for RV32/
RV64 respectively. This allows the macro to replace current use of ARCH_RV64
in riscv_mtimer.c.
The new MMIO_BITS config is a derived one, and for RiscV chips with
equal CPU and MMIO widths there is no need to explicitly set it as the
default rule will do that. Only chips with different CPU and MMIO widths
need set it in Kconfig.
So by design this change should be safe but RiscV ports should be checked.
"ostest" verification has been done for:
- canmv230/nsh
- rv-vivt/nsh
- rv-virt/nsh64
configuration generation and manual check of derived RV_MMIO_BITS has been
done for:
- star64/nsh
- arty_a7/nsh
- bl602evb/nsh

SiFive document: "ECC Error Handling Guide" states:
"Any SRAM block or cache memory containing ECC functionality needs to be
initialized prior to use. ECC will correct defective bits based on memory
contents, so if memory is not first initialized to a known state, then ECC
will not operate as expected. It is recommended to use a DMA, if available,
to write the entire SRAM or cache to zeros prior to enabling ECC reporting.
If no DMA is present, use store instructions issued from the processor."
Clean the cache at this early stage so no ECC errors will be flooding later.

When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.
I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.
