This patch adds a way to configure PLL frequencies. The configuration is
given by board logic.
These values should only be modified by the bootloader, but we don't have
that yet so the flag is never activated.
1. pm configuration demonstrates the use of power management present on the ESP32-S3.
2. You can use the pmconfig command to test the power management, for details look at
``Documentation/platforms/xtensa/esp32s3/boards/esp32s3-devkit/index.rst``

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.

This is copy of raspberrypi-pico with all occurences of raspberrypi replaced by
w5500-evb. Only the usbnsh defconfig is available, which is based on the
raspberrypi-pico:usbnsh defconfig, but enables the WIZnet W5500 Ethernet chip.
TCP/IP for IPv4 and IPv6 is enabled.

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 esp32s3 targets and removes the need
for running 'make bootloader' command for it.
Other related fix, but not directly to Simple Boot:
- Instrumentation is required to run from IRAM to support it during
initialization. `is_eco0` function also needs to run from IRAM.
- `rtc.data` section placement was fixed.
- Provide arch-defined interfaces for efuses, in order to decouple
board config level from arch-defined values.

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.

This commit updates the Wi-Fi and the BLE driver of ESP32. Most of
the changes rely on using the common sources and header files for
xtensa-based Espressif's SoCs.
The new Wi-Fi driver supports WPA3-SAE for both Station and SoftAP
mode. BLE's coexistence mode was enhanced according to the latest
libraries.
Please note that other sources required minor changes in order to
be compatible with the common sources.

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.
Adds board definition for imx93-evk board
- 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
which boots the SoM to nsh console
- A bootloader is required, u-boot has been tested
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
simultaneously when not using the processor Security Externsions.
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);

Currently only FLAT mode development can enjoy cmake build system. This
patch tries to add initial kernel mode support. It can build NuttX kernel
and libproxies.a, the latter will be further checked though.
This can already help to build an AMP remote node image as it can share
userland apps living in the AMP master node.
Major changes:
- in top folder:
- CMakeLists.txt adjust for KERNEL mode, separate from PROTECTED mode.
- in `syscall`:
- CMakeLists.txt add mksyscall target for stubs/proxies generation
- in `syscall/stubs`:
- CMakeLists.txt use dependency to mksyscall
- in `syscall/proxies`:
- CMakeLists.txt use dependency to mksyscall
- in `arch`:
- CMakeLists.txt separate KERNEL from PROTECTED mode.
- in `arch/risc-v/src`:
- CMakeLists.txt separate from PROTECTED mode, add sub folders.
- in `arch/risc-v/common`:
- CMakeLists.txt add sources and sub-folders for KERNEL mode.
- in `arch/risc-v/k230`:
- CMakeLists.txt add sources for KERNEL mode.
- in `boards/risc-v/k230/canmv230/src`:
- CMakeLists.txt adjust k230 specific scripts for kernel mode.
New additions:
- in `arch/risc-v/src/nuttsbi/` add CMakeLists.txt
- in `arch/risc-v/src/common/supervisor/` add CMakeLists.txt

This driver is used with QEMU, to make it possible
to use networking.
This is not the MAC in ESP32, however, it can be used with QEMU.
The code was shamelessly copied from 31dac92e5f
this partly revert 4123615621 which works OK for PCI serial and network cards
but breaks QEMU EDU due to usage of sem and usleep in IDLE thread context.
Another solution will be provided later.

When an application is being loaded `up_addrenv_create ` calls
`create_region` to create the address environment. Only the first
entry is mapped when the region is created. Virtual memory that is
not mapped will trigger an exception when accessed. Other memory
pages are allocated and mapped on-demand. This enables setting
larger heap and stack for the process without compromising the
overall system memory.
Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.
We will first check whether the target file path exists. If it does not exist, we will check whether the common exists. If not, we will restore the path that should be spliced at the beginning.
