AVR DA/DB family chips have single interrupt vector for all changes
on an I/O port. This poses problem when multiple drivers want to claim
the same interrupt (might happen for example with button and discrete
joystick drivers using pins on the same port.)
The I/O multiplexer solves it by providing interface similar
to irq_attach. However, it allows registration of multiple handlers
for the same interrupt vector with additional information recording
which pins should be serviced by each handler.
Only handler for pins that triggered the interrupt is then called.
Initial support adds chip specific files like Kconfig, flags for the compiler,
and basic functionality like system timer. Some files are stubs derived
from corresponding ATmega files but without the functionality they are
supposed to add (to be done in later patches)
Part of the work is altered copies of corresponding files for ATMega MCUs.
Initially supported is AVR128DA28.
This commit introduces the tagging system into the STM32 family of chips
by tagging all chips with their appropriate chip type/family.

Add kernel build (target imx93-evk:knsh) to i.MX93 EVK.
This target is preconfigured for use with AHAB boot (see
https://spsdk.readthedocs.io/en/latest/examples/ahab/imx93/imx93_ahab_uboot.html)
as a replacement of U-Boot proper (BL33 at EL2), hence
the load address is set to 0x80200000.

Introduces `sphinx-tags` to the documentation system, allowing
individual pages to be tagged for better searching. The examples in this
commit introduce the `chip:*` tag for indicating the chip a board uses,
as well as the `experimental` tag for indicating experimental boards and
features. Other tags indicate supported peripherals for boards, such as
`wifi` and `ethernet`.

It is not recommend to just copy defconfig to .config instead of
running ./tools/configure.sh. The configure script will do more
than just copying the defconfig, it will create backup config,
it will check if apps/ dir exists, etc.

This updated the command used for running the openocd-esp32 for
all the supported Espressif's SoCs. It enables using SW-defined
breakpoints.

Renaming "modlib" to "libelf" is more in line with the implementation content,
which makes it easier for individual developers to understand the capabilities of this module.

This commit adds support for the BMP180 sensor on the
STM32F401RC-RS485 board and updates the board documentation
accordingly. It also enables the BMP180 UORB driver in the
STM32 common logic.

Use configuration CDCACM_DISABLE_TXBUF or CDCACM_DISABLE_RXBUF to choose
whether to use usb req buffer as the serial buffer. Since the default
value is n (not using req buf), the original configuration of buf is valid.
This reverts commit 21c8ed80bd.
This PR adds support for the PINE64 Yuzuki Avaota-A1 SBC,
based on Allwinner A527 Arm64 SoC.
Most of the code was derived from NuttX for
QEMU Arm64 Kernel Build qemu-armv8a:knsh.
The modified code is explained here:

Change the ESP32S3-WROOM-2-N16R8V to ESP32S3-WROOM-1-N8R2.
Reason: not testing on 16MB but successfully tested smaller flash and PSRAM.
Also updated documentation on this defconfig.
