- Add config "ARCH_USE_S_MODE" which controls whether the kernel
runs in M-mode or S-mode
- Add more MSTATUS and most of the SSTATUS register definitions
- Add more MIP flags for interrupt delegation
- Add handling of interrupts from S-mode
- Add handling of FPU from S-mode
- Add new context handling functions that are not dependent on the trap
handlers / ecall
NOTE: S-mode requires a companion SW (SBI) which is not yet implemented,
thus S-mode is not usable as is, yet.
RISC-V GCC is configured with --enable-initfini-array so it emits an
.init_array section instead of .ctors

## Summary
`esp32c3_spi2_cmddata()` implements SPI Cmd/Data `SPI_CMDDATA()` for only 3 LCD drivers: ST7735, ST7789 and GC9A01.
This patch removes the check for LCD drivers, so that SPI Cmd/Data will work for all LCD drivers.
More details: https://github.com/apache/incubator-nuttx/pull/5898
## Impact
This change impacts LCD drivers that call `SPI_CMDDATA()`.
Previously `SPI_CMDDATA()` would fail with `ENODEV` for LCD drivers other than ST7735, ST7789 and GC9A01.
After patching, `SPI_CMDDATA()` will work correctly with all LCD drivers.
## Testing
This is a minor patch so no testing is needed.

Move the target specific memory map to a separate file so there is no
need to copy&paste the __xxram_start etc linker symbols to each file
that needs them.
Also add MMU flags for I/O and kernel areas, they will be needed
when the kernel runs with virtual addresses also.

State of problem:
- Some drivers that do not support write operations (does not
have write handler or ioctl do not perform any write actions)
are registered with write permissions
- Some drivers that do not support read operation (does not
have read handler or ioctl do not perform any read actions)
are registered with read permissions
- Some drivers are registered with execute permissions
Solution:
- Iterate code where register_driver() is used and change 'mode'
parameter to reflect the actual read/write operations executed
by a driver
- Remove execute permissions from 'mode' parameter

We load the code into NuttX heap, which can be too far from
the usual code segments for the relocation types used by the
default "small" model to reach.
This worked around out of range relocations seen with my local app.
The image must be placed into:
boards/risc-v/mpfs/icicle/include/boot_romfsimg.h
The image is mounted by mpfs_bringup, which is run by the application
itself, or by board_late_initialize() in the case when
CONFIG_BOARD_LATE_INITIALIZE is defined, e.g. with CONFIG_BUILD_KERNEL
NOTE: THIS ONLY WORKS WHEN KERNEL RUNS IN M-MODE FOR NOW
This frees the PMP for other use, e.g. HART memory separation.
The page tables are statically allocated, 1 per level.
This feature is now behind CONFIG_MPFS_USE_MMU_AS_MPU, because
only the MPFS target supports this (others are not tested).
If the MMU is used for memory separation within a HART, the PMP must
still be configured to allow user access to the memory mapped for the
HART, because PMP *rekoves* access by default. At this point all of
the user memory as well as the kernel RAM are opened.
A more flexible solution for PMP configuration will follow.
The old implementation used the default ld.script for the kernel side
which did not obey the memory.ld limits whatsoever.
Also, provide the user space addresses from the linker script to get rid
of the pre-processor macros that define (incorrect) default values for
the user space composition.
Some of the configuration options have changed, so update this
config file accordingly.
In this example config, the following hart configuration takes
place:
hart1: 0xafb00000 (Another NuttX)
hart2: unused
hart3: 0x80200000 (u-boot and Linux kernel)
hart4: 0x80200000 (u-boot and Linux kernel)

By using a standard extension for Makefiles (https://www.file-extension.info/format/mk), editors will auto-format files.
This change will also improve developer ergonomics when searching for specific files
Verified locally that build still works, CI will verify more!
Polarfire Icicle board has only (128K - 256) bytes for the bootloader
in the non-volatile eNVM. This space is barely enough for running NuttX.
If OpenSBI is selected, it will be placed in DDR. This all means the
nuttx.bin file grows into gigabyte size, filling the unused space (ddr -
envm) with zeroes.
The memory layout is as follows:
MEMORY
{
ddr (rx) : ORIGIN = 0x80000000, LENGTH = 4M
envm (rx) : ORIGIN = 0x20220100, LENGTH = 128K - 256
l2lim (rwx) : ORIGIN = 0x08000000, LENGTH = 1024k
l2zerodevice (rwx) : ORIGIN = 0x0A000000, LENGTH = 512k
}
OpenSBI library is used as a separate binary, which is stored into
eMMC or SD-card. It is then loaded into its precise location in DDR.
Thus, we separate OpenSBI from NuttX and end up with two images
by utilizing the objcopy options:
--only-section=sectionpattern (-j in short)
--remove-section=sectionpattern (-R in short)
This is only valid when CONFIG_MPFS_OPENSBI is set.
