Current LITEX_LAST_IRQ looks like a typo that blocks compilation of
`arty_a7/knsh` configuration.
This fixes the build but I have no such device for test.
Found it was LITEX_IRQ_LAST before commit #ee84ea3 so likely typo was
introduced by then.

The lowest bit of the thumb instruction is 1 by default, which is used to distinguish arm instructions and thumb instructions.
Fixed the problem of misalignment of symbol table when performing binary search
In arm, the lowest bit of the instruction is 1, which is a thumb instruction, and 0, which is an arm instruction.
The nm command was used in mkallsym.sh before, and the result it will return will set the lowest bit of the thumb instruction to 0. There will be a one-byte deviation during binary search, so mkallsyms.py will also set the lowest bit to 0 according to the previous format.
```sh
arm-none-eabi-nm -Cn nuttx | grep hello
0801c384 T hello_main
arm-none-eabi-objdump nuttx -t |grep hello
0801c384 g F .text 0000004c hello_main
arm-none-eabi-readelf nuttx -s |grep hello
4558: 0801c385 76 FUNC GLOBAL DEFAULT 1 hello_main
```
However, in the following case, when you need to find the function address according to the symbol name and execute the corresponding function, the lowest address obtained is 0. It will follow the arm instruction, causing an exception.
```c
void sym_test(void)
{
printf("call sym_test\n");
}
int main(int argc, FAR char *argv[])
{
FAR void *addr = sym_test;
printf("sym_test:%p %pS\n",addr, addr);
printf("sym_test - 1: %pS\n", (char *)addr - 1);
printf("sym_test + 1: %pS\n", (char *)addr + 1);
size_t size;
void (*func)(void);
const struct symtab_s *sym = allsyms_findbyname("sym_test", &size);
printf("sym_test:%p %pS\n",sym, sym);
func = sym->sym_value;
func();
return 0;
}
```
Therefore, you need to change mkallsyms.py back to the correct result and correct the binary search.

The implementation of the RISC-V Timer for BL808 SoC is incomplete. This PR implements the BL808 RISC-V Timer by calling OpenSBI. The code is derived from NuttX for RISC-V QEMU.
The implementation of `up_timer_initialize` with OpenSBI is explained in this article: https://lupyuen.github.io/articles/nim#appendix-opensbi-timer-for-nuttx
This tries to mirror the following change.

libs/libxx: Enforce RTTI for building libcxxabi
It is okay for the application to be built without RTTI (-fno-rrti), but
libcxxabi requires RTTI at least for the library.

libcxx: Remove exiting patches and update libcxx version to 15.0.7
- Add __config_site for NuttX.
In libcxx 12.0.0. CMake concatenated __config_site with _config,
which enabled NuttX to build without its inclusion. In 15.0.7, this
file is configured by CMake and included explicitly in __config.
- Add additional include directories.
- Mute always_inline warning.
- Make the download of libcxx/libcxxabi configurable
```
Changes:
- Documentation/platforms/risc-v/k230 revised for both modes
- arch/risc-v/include/k230/irq.h add S-mode IRQs
- under arch/risc-v/src/k230 folder:
- Make.defs drop use of k230_exception_m.S
- hardware/k230_clint.h add S-mode defs, revised freq
- k230_head.S unified flat/kernel mode support
- k230_irq.c add S-mode support with debug dump
- k230_mm_init.c revised for K230 S-mode
- k230_start.c revised for flat/s-mode,
- arch/risc-v/src/k230/k230_timerisr.c unified flat/s-mode support.
- under boards/risc-v/k230/canmv230 folder:
- configs/nsh/defconfig fix RAM size
- include/board_memorymap.h cleanup for S-mode
- src/.gitignore ignore romfs_boot.c
- src/Makefile add romfs support
Renames:
- under boards/risc-v/k230/canmv230/src/ folder:
- canmv_init.c from k230_appinit.c making room for more k230 devices
Dropped:
- under arch/risc-v/src/k230/
- k230_exception_m.S as hybrid mode not ready yet.
New files in boards/riscv/k230/canmv230:
- configs/knsh/defconfig S-mode config
- scripts/ld-kernel.script S-mode linker script
- src/romfs.h User space ROMFS defs needed in S-mode
- src/romfs_stub.c Stub ROMFS image

hostfs has its copies of some of nuttx definitions with different
names to avoid conflicting with the host OS definitions.
sometimes people only modifies one of them and forgets updating
another. eg. https://github.com/apache/nuttx/pull/11445
this commit introduces some assertions to detect that kind of
mistakes.
This is to align with ARCH_KMAP_VBASE by source codes.
It also fixes fake warnings from `tools/refresh.sh`.

this is to adjust levels of a few of them based on debugging
experiences. These non-critical logs were marked as errors. So we
likely can adjust them as warnings so that real errors can

after the CI environment is upgraded to Ubuntu 22 and GNU make is upgraded to 4.3,
`warning: jobserver unavailable: using -j1. Add '+' to parent make rule.` warning appears.
this because when executing a shell in Make, the new shell created will not inherit the parallel environment of the parent shell(jobserver).
in our case:
```
$ make olddefconfig
this execute into Unix.mk twice,
because it will call make clean_context in its target
olddefconfig:
$(Q) $(MAKE) clean_context
```
We replace the shell call with the target of the Makefile
