The Raspberry Pi 4 board can boot the image from USB memory.
But current meta-raspberrypi supports only SD boot.
This commit allows switching SD boot to other device.
For example, if you want to use USB boot, please define
the following parameters in your conf/local.conf file.
CMDLINE_ROOT_PARTITION = "/dev/sda2"
BOOT_MEDIA = "usb"
v4: Update extra-build-config.md to explain more detail for new variable.
v3: Changed variable name to "BOOT_MEDIA" (was "BOOT_DEVTIPE").
v2: Set existing microSD parameter as default. User can overwrite
some parameters.

When RPI_USE_U_BOOT is set to 1, if enable_uart is not set to 1 in config.txt
then the board won't boot (Resolves agherzan#1189).
This requirement only affects the following boards:
- Raspberry Pi Zero W
- Raspberry Pi 3 32 & 64 bit
- Raspberry Pi 4 32 & 64 bit

Explains that PREFERRED_PROVIDER_ffmpeg/vlc
can be used to select an implementation of ffmpeg
or vlc. Also adds information on how vlc mmal_vout
plugin could be utilized. As well as how to expose
rpidistro-vlc.

The `rtc` machine feature is "considered" by default for all the
machines we provide until now. This can confuse people who would want an
RTC device attached to a RaspberryPi board[1]. Clarify this via
documentation.

This is the result of automated script conversion:

Added imx219.dtbo file in the overlays, and added dtoverlay in
/boot/config.txt define based.
To enable Sony Raspberry pi camera imx219 sensor, need to set
the variable RASPBERRYPI_CAMERA_V2 as 1.
In future, we can add any camera overlays here to support and
use them with libcamera.

Using SDIMG_COMPRESSION variable to choose compression type for
produced images is deprecated. IMAGE_FSTYPES should be used instead.
This patch removes any reference to SDIMG_COMPRESSION variable
within the build documentation.

* use INITRAMFS_SYMLINK_NAME from new kernel-artifact-names.bbclass
instead of KERNEL_INITRAMFS
* the documentation says that KERNEL_INITRAMFS should be used to
define extension of initramfs, but in linux-raspberrypi.inc it's
defined only to 1 or empty based on INITRAMFS_IMAGE_BUNDLE variable
and I don't see any code in meta-raspberry or oe-core which would
use KERNEL_INITRAMFS to actualy name the initramfs artifact to create:
${DEPLOY_DIR_IMAGE}/${KERNEL_IMAGETYPE}${KERNEL_INITRAMFS}-${MACHINE}.bin
used in classes/sdcard_image-rpi.bbclass
* also fix the assumption that there is -${MACHINE} suffix in:
${DEPLOY_DIR_IMAGE}/${KERNEL_IMAGETYPE}${KERNEL_INITRAMFS}-${MACHINE}.bin
because that's defined as KERNEL_IMAGE_SYMLINK_NAME and some DISTROs
might use different value
* this depends on oe-core changes which were merged today:
http://git.openembedded.org/openembedded-core/commit/?id=7d0ef0eaa1bfe97015a774c26f5791622e7e8b12

For raspberrypi3-64 we need to use the Image or Image.gz format with u-boot
instead of the legacy uImage format. We also need to issue the 'booti' command
to boot the kernel instead of 'bootm'.

We provide a lot of variable examples as code blocks in the following
format:
some text: `Variable`
or
some test:
`Variable`
Which is not as pretty as (when converted to html/pdf):
some text:
Variable
Converted all and hoppefully this will improve readability a bit.

The top-level README document has got pretty unwieldy and so we need to
switch to add some more structure to our documentation. The first step
is to split out sub-sections of the README document into separate files
in a new 'docs' directory.
Whilst splitting up the README, we can also take the opportunity to tidy
things up and fix a couple of typos.
