This adds enablers for setting various clocks to some default
values. Also, this provides helpers to grant nonsecure access
to a number of clocks. Bootloader may utilize these to make
the system boot in a deterministic manner.

This commit implements a character driver for the general purpose ADC of the BL808, based on the hardware scanning functionality. The driver supports setting different conversion resolutions and the order of channels to be scanned via menuconfig.
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 removes deprecated code and makes this bootloader
configuration as default for esp32 targets and removes the need
for running 'make bootloader' command for it.

This commit modifies the existing serial driver to add support for the remaining UARTs on the BL808. It also introduces support for setting baud rate, character length, stop bits, parity, flow control and which serial port acts as the console.
This change implements a system for allowing the D0 core (which runs NuttX) to receive forwarded interrupts from the M0 core. This makes it possible for drivers that rely on interrupts to work with peripherals attached to the M0 core.
As suggested in PR:12530, changed the default names of ESP32S3WROOM chips to ESP32S3WROOM1N4,
ESP32S3WROOM2N16R8, ESP32S3WROOM2N32R8, ESP32S3MINI1N8.
Also regenerated all the defconfigs for board configurations.

This provides an alternate tickless scheduling method, which uses the riscv
mtimer as a timebase, allowing the time and timeh registers to used

it is a more performant option, but currently has the potential issue

Add a simple allocator for DMA safe memory. It will provide contiguous
blocks of memory with D-Cache line size alignment.
NOTE: The optimal granule size is the D-Cache line size (64), but due
to restrictions in the granule allocator this would result in a maximum
block size of 2K only, thus use 256B granules instead givin 8K max block
size.
Once the granule allocator is fixed this limitation can be removed.
These configs are changed based on below rules.
1. always enable +CONFIG_LV_USE_NUTTX=y
2. If touchpad is used, enable +CONFIG_LV_USE_NUTTX_TOUCHSCREEN=y
3. enable log by +CONFIG_LV_USE_LOG=y
4. If -CONFIG_LV_MEM_CUSTOM=y previously defined, replace it with +CONFIG_LV_USE_CLIB_MALLOC=y +CONFIG_LV_USE_CLIB_SPRINTF=y +CONFIG_LV_USE_CLIB_STRING=y
5. If -CONFIG_LV_PORT_USE_FBDEV=y, default config is for fbdev. If -CONFIG_LV_PORT_USE_LCDDEV=y, +CONFIG_LV_USE_NUTTX_LCD=y
6. Remove all -CONFIG_LV_TICK_CUSTOM=y -CONFIG_LV_TICK_CUSTOM_INCLUDE="port/lv_port_tick.h"
7. If -CONFIG_LV_PORT_LCDDEV_DOUBLE_BUFFER=y, replace it with CONFIG_LV_NUTTX_LCD_DOUBLE_BUFFER=y. For fbdev, double buffer is automatically detected.

The qemu-rv use a small init code for M mode in kernel build.
It is hard-coding and is difficult to change. Due to the fact,
introduce a already mature SBI implement (e.g OpenSBI) to
replace existing code is a better choice.
This patch introduce some change for qemu-rv:
1. use SSTC to provide time interrupt in kernel build
2. remove uncessary M mode trap.

nuttx for any core, but force boot core to start core 0 and
let core 0 do the initialization.

This patch allows user to simply select which GPIOs he wants to use
and access them via /dev/gpio_a0 or similar device with standard
gpio driver.
By default gpio names match pin names printed on the board. So when
enabling A3 pin, it will show as /dev/gpio_a3 in runtime. This name
can be changed in kconfig.
User can also select pin function (input, output, interrupt) as well
as standard pin settings like, pull up/down, output type
pushpull/open drain etc.
All pins that are exposed via boards goldpins are listed in Kconfig.
Extra pins that are supported by chiip but are not exposed for easy
usage are not listed.
To have this nice Kconfig configuration and for things to be easily
debugable/understandable it requires code to have big Kconfig and
header file with all possible definitions
Because of file sizes I decided to split gpio related kconfig and
header into separate files. Otherwise it would really make original
files hard to read and find anything.

RTC data was not being correctly placed on RTC's memory data due to
linker issues. Also, the image's RTC memory segment was not being
properly parsed by the bootloader.
This commit implements the common RMT driver (already available for
the other Espressif's xtensa-based devices) for ESP32.
This allows us to have a proper separation between the lower and
upper-half drivers and use the 'ws2812' example to drive WS2812 RGB
LEDs.

As __start must be placed at a precise location, a separate, explicit
input section is needed to guarantee this.
Why is this an issue ? NuttX uses --entry=__start which puts __start in
its correct location, but out-of-tree builds won't work, so it more robust
to use an explicit section for the startup code and enforce its placement
in the linker script.

- Support for the Cortex-A55 core in i.MX93, support for the Cortex-M33
core is _not_ provided
- "nsh" profile is provided, this includes a minimalistic feature set

Purpose: make the the os crash when busyloop with interrupt disable
Follow the arm gicv2 spec, if we want to use the IRQ and FIQ

We should:
1. IRQ to Group 1 and FIQ to Group 0;
2. Set CICC_CTLR.FIQEn to 1;
Then in NuttX:
1. implement the arm_decodefiq and directly crash in it;
2. provide interface to change the IRQ to FIQ, e.g. change the
watchdog IRQ to FIQ, so the watchdog can trigger even with the
interrupt disabled (up_irq_save() called);
