After warm reset the interrupt source in the HW block is not explicitly
cleared, thus once the interrupt source is enabled the old / stale interrupt
fires immediately.

This commit fixes building native MCUboot from sources by getting
the required sources from `esp-hal-3rdparty` repository and enable
building MCUboot and using it as the 2nd stage bootlaoder.
- A pre-built IDF bootloader is used by default;
- `ESP32C3_PARTITION_TABLE` requires the IDF bootloader to be built
from sources.
- Native MCUboot also can be used to boot the device. It will be
built from sources and depends on !ESP32C3_PARTITION_TABLE.
- A pre-built IDF bootloader is used by default;
- `ESP32S3_PARTITION_TABLE` requires the IDF bootloader to be built
from sources.

Simple boot is a method of booting that doesn't depend on a 2nd
stage bootloader. Please note that some of the ESP-IDF bootloader
features are not available using simple boot, such as partition
tables and OTA: most of these features are implemented in NuttX
and MCUboot.

This commit refactors DAC driver. The functionality remains the same
but driver start up is now done in dac_setup (after application called
open function) instead of sam_dac_initialize (called from BSP). This
ensures that driver does not take resources (timer, interrupt) until
opened. Implementation of dac_shutdown is also provided, therefore
the driver frees resources once closed.
This change is consistent with other drivers implementation.

USART peripheral can work in SPI mode as well. This commit adds support
for such functionality. Only 1 slave device is supported by the
peripheral therefore board level does not have to ensure correct CS
setup.
The usage of the peripheral is the same as with other SPI drivers.

This commit adds basic support for iC-JX expander in SPI mode. The

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`.
Ubuntu stock toolchain `gcc-riscv64-unknown-elf` complains about

If a TX DMA completion interrups a forground write.
The TX DMA completion can start a dma_send and it will
then followed by the forground write's dma_send
stoping the,then in progress DMA.
By atomicaly marking the tx dma busy, the forground
write will not perform the dma_send, and will only
enqueue the data. At the next TX dma completion any
data pending in the tx queue will be sent

ESP32 is supported on NuttX starting from chip revision 3.0. This,
however, didn't prevent the user from using older chip revisions,
which caused unexpected behaviors. This commit checks chip revision
before finishing booting NuttX.
This commit is intended to update the EFUSE's register content and
update related configs:
- Remove duplicated configs from `esp32_soc.h`;
- Add missing header files from APB registers;
- Add missing macro definitions from EFUSE;
- Update related code to use the new macros;
The logic of the conditional expression that determines whether
the QH is a target QH or not is reversed in the process of canceling
a transfer in INPROGRESS state.
Therefore, the QH in INPROGRESS state is not released and subsequent
communication is not successful.
Checked with CDC-ACM driver and cu command.

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.

This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.
A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2
The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info
The Linux gatttool was used to connect over wireless.
With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I
Connect to the device using:
connect
Read the device name using the GAP device name UUID:
char-read-uuid 2a00
Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
