As long as the GNSS feature is not used, GNSS RAM can be used as general memory.
This memory is 640KByte total, which is lower performance than the application RAM.
It is possible to locate text, data and bss into GNSS RAM and to use as heap area.
Since there were some cases in which the current modem reset
sequence did not reset the modem, the reset was ensured by
executing power off and power on of the modem.
Enable with ./tools/configure.sh -l esp32-devkitc:dac
DAC channel 0 = GPIO 25
DAC channel 1 = GPIO 26
default path: /dev/dac0
Resolution 8 bits = values 0~255
Voltage: 0~Vref
The reference voltage 'Vref' here is input from the pin VDD3P3_RTC
which ideally equals to the power supply VDD (3.3V).
Weak function sometimes can't have strong implementation linked.
This patch uses NUTTSBI_LATE_INIT config and normal function instead
to avoid those issues.

This adds support for creating an early frame buffer and primatives for
writing to this frame buffer as a console. This does require the font
infrastructure as well as multiboot2.
Additionally this can now be used with a UEFI bootloader long as it
boots NuttX via Multiboot2. There does seem to be a PCI interrupt
issue when running in UEFI mode.
I was able to boot my laptop using this and see PCI devices enumerate.

x86_64: Add conditionals around the multiboot framebuffer
Squashed commits:
1. Porting prior PCI work in place of jailhouse code
At this point the PCI enumeration works for x86_64 including over
pci-pci bridges.
Running QEMU with this configuration we see the bridge and the
device on the bridge. It also detected the qemu test device

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

- 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.

fix typo
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
which is the string "Apache NuttX"
