On K3 SoCs the A53 cluster does not own device power, clocks, resets or
interrupt routing; these are managed by the DM/TIFS firmware and requested
over TISCI through the secure-proxy mailbox. Add:
- a TISCI client (secure-proxy transport plus device/clock/reset helpers)
- a GPIO driver for banks 0/1 with pad mux and TISCI power-on
- an OMAP-I2C driver for the main-domain I2C controllers
and wire them into the PocketBeagle2 and BeaglePlay bring-up.
Tested on PocketBeagle2 (SYSFW 11.2.5) with the TechLab cape attached:
nsh> i2c bus
nsh> i2c dev -b 0 0x03 0x77 # I2C0 detects onboard 0x20 and 0x50
nsh> gpio -o 1 /dev/gpio3 # drives a user LED; read back with:
nsh> gpio /dev/gpio3

This commit includes BMP280 driver registration on I2C1 in the RPi4B
bringup logic _if_ the user selects the board-level configuration option
(so as to not interfere with any user's custom implementation of
interfacing with this sensor). A configuration is added with the BMP280
registration, example program and `uorb_listener` that is also
documented.

The documentation is now updated to reflect the new EMMC support. I have
also improved the format to match the standard board documentation
template, and included better support descriptions for features that
have varying levels of implementation.

Initial I2C implementation such that I2C sending and receiving now
works well enough to use the BMP280 driver for a BMP280 device connected
to any of I2C0-I2C6 on the default pins. I2CTOOL also works for these
interfaces.
Functionality for "no stop" and "no start" options is not present.
Implementing that is not clear from the peripheral datasheet and will be
a challenge.

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.
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`.

model. Part of an I2C driver which can only read, boiler-plate for a SPI
driver, and a GPIO driver with limited pins. Some tools are present for

This does the following:
1. Fetches mkimage_imx8 (same used with imx9) source code
2. Fetches the ELE / AHAB binary
3. Extracts the ELE / AHAB binary
4. Compiles the mkimage with hostcc
5. Utilizes the mkimage tool to create a bootable SD image,
combining the ELE / AHAB image with the NuttX bootloader
6. dd is used to prepend empty space in place of BL31
7. Outputs sdimage.img which is a bootable binary
8. Removes all binaries, sources code images that have been
downloaded

It is advisable to set bootdelay to 0 when using bootcmd to disable
dcache on u-boot. Using bootdelay -1 will definitely work as it disables
bootcmd altogether (and leaves the dcache enabled). This step is added
to remove confusion.
