This enables the use of the cryptographic accelerator within
the ESP32. The support algorithms are: SHA1, SHA256, SHA384
and SHA512.

Migrated teensy 2.0 README.txt to RST format. Moved common tool-chain
information to the chip page and provided back-link.

This implements an interrupt-based SPI driver for the BCM2711 SPI
interfaces (excluding auxiliary SPI interfaces). Only tested on SPI0
since proprietary firmware does not initialize any other SPI interfaces,
and doing so will require reverse engineering.
The document context-switch-notes.rst was leaking into "Supported Platforms"
table of contents. To fix this, it was moved to separate common directory
and referenced from AVR index.rst
Similar to that, the gpio_intr_mux.rst document was leaking into list
of supported AVR families. This too was fixed by moving it to separate
docs directory.
The change was tested by building the Documentation using make html

After a mailing list suggestion, the indirection that enabled
ARCH_TOOLCHAIN_GCC only when user requested it is removed.
The indirection was a safety measure for chips and boards with linker
scripts that (possibly) do not handle keeping for example .vectors
section even if the linker considers it unreferenced.
Instead, all existing configurations now disable
CONFIG_DEBUG_OPT_UNUSED_SECTIONS to prevent the linker from removing
any code. (Preserving previous behaviour.) This can be removed again
at some point after making sure that corresponding linker script
only removes code that is truly unused.

This patch adds additional information to breadxavr board for AVR DA family
development. The text now covers how to use Button input driver and also
adds some information about using the hardware.

Unlike the Hello, world example, the NSH configuration can serve
as a starting point for testing other examples.

Installation instructions, license exceptions and supported features
of the RP2040 common among all boards have been moved exclusively to the
rp2040/index.rst file. Board documentation links back to the primary
source for installation instructions.

This commit adds the documentation for the Seeed Studio XIAO ESP32C6
board. It includes examples for NSH, USBNSH, GPIOs and Wifi.

This patch adds definitions for listed chips. No other changes are needed
as the chips are similar to the previously supported AVR128DA28 and all
that is needed is some definitions for extra peripherals.
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.
