oe-core has completely re-written the fitImage support starting roughly at
commit [1], update meta-rockchip to match.
Most of the MACHINEs in meta-rockchip use a fitImage for the kernel, but
some don't. Create a boolean variable (RK_KERNEL_FITIMAGE), enabled by
default, to keep track of which ones do and which ones don't. Use this
variable to decide how to configure various image-related fields.
Build tested with all meta-rockchip MACHINEs both with and without RAUC.
Run tested on the following with RAUC configured:
- nanopi-m4b
- nanopi-r2s
- radxa-zero-3e
- rock-pi-4b
- rock-pi-e
- rock-pi-s
Run tested on the following without RAUC:
- radxa-zero-3e
- rock-pi-e
- rock-pi-s

v4l2codecs is the gstreamer plugin for V4L2 stateless video hardware
decoding. The Rockchip SoCs that have a VPU all seems to be based on
Hantro, RKVDEC or RKVDECv2, all stateless encoding/decoding VPUs.
Therefore, let's enable VPU decoding in Gstreamer whenever possible,
when the SoC supports it.
PX30, RK3066, RK3188, RK3288, RK3328, RK3399, RK356x and RK3588(s) all
have at least one Hantro VPU.
RK3328, RK3399, RK356x and RK3588(s) all have at least one
RKVDEC/RKVDECv2 VPU (though not necessarily supported in the upstream
kernel just yet).
=== PX30
Tested on PX30 Ringneck with with Haikou+Haikou Video Demo adapter:
$ gst-launch-1.0 filesrc location=$FILE ! parsebin ! v4l2slh264dec ! waylandsink
with FILE storing the path to any h264 file, e.g.

- weston
- gstreamer1.0-plugins-bad (for waylandsink and v4l2slh264dec)
- gstreamer1.0-plugins-base (for parsebin)
A few frames are dropped every other second for 1080p but otherwise
smooth.

This example uses a simple A/B + D scheme (i.e. two root partitions and a

This adds closed-tpl to MACHINEOVERRIDES if ROCKCHIP_CLOSED_TPL is set

On systems where KERNEL_IMAGETYPE is not set to fitImage, one needs to
either pass an DTB or a path to a directory where DTBs are located on
the rootfs.
When FDT property in extlinux is provided, FDTDIR isn't used (and
actually u-boot-extlinux-config doesn't even write it to the
configuration file).
When relative paths are used, they are relative to the directory where
extlinux.conf is stored[1]. Since the DTBs are stored in /boot, just
providing the filename of the DTB won't work because extlinux in U-Boot
will search for it in /boot/extlinux. We should therefore either use ../
prefix for relative paths or use /boot to make it absolute. /boot is
more explicit and easily parseable, so let's use the latter.

If an image doesn't include kernel-modules, the kernel-image package
won't be installed by default. This means that no
kernel-image-${KERNEL_IMAGETYPE} package will be pulled in, resulting in
neither fitImage nor Image (or uImage, or zImage, or...) making it to
the filesystem, rendering the image non-bootable.
For non-fitImage scenarios, we currently expect DTB-less kernel images
(no bundle, like in uImage) so we also need to pull in the DTB via the
kernel-devicetree package.
Those packages used to be pulled in by the wic plugin through the

U-Boot has the ability to store its environment variables to a permanent
storage device. Whether or not it does so for any one specific device
depends on whatever settings are enabled in that specific device's
defconfig. In order to definitively configure U-Boot to be able to store
its environment into the device from which it boots, for any device
supported in this BSP, simply add the following to MACHINE_FEATURES:
rk-u-boot-env
If enabled, there is now a second choice to make: should the build also
include the U-Boot environment in the image or not? The default environment,
as generated by U-Boot, can be included in the generated wic image. If it
is included, then flashing the image will also flash the default U-Boot
environment variables and settings, wiping out anything that might have been
there already. If it is not included then your device will either continue
using whatever environment happens to be there (if valid), or will not use any
stored environment if the stored environment has not been set or is invalid.
The variable which governs this behaviour is:
RK_IMAGE_INCLUDES_UBOOT_ENV
By default this is set to "0", meaning that by default the image does not
contain the U-Boot environment. To enable this behaviour, enable this
variable. This variable only takes effect if rk-u-boot-env is listed in
MACHINE_FEATURES, and has no effect otherwise.
The script:
scripts/dump-uboot-env-from-yocto-image.sh
can be used on a rockchip wic image to see the contents of the U-Boot
environment partition at build time.
Tested by booting the same image on both eMMC and SDcard with the following
devices, verifying the ability to read and write the U-Boot environment in
both U-Boot and Linux user-space, and that changes made in one are seen in the
other:

Upstream kernel support for both the rock-5a and rock-5b landed in version
6.5. Nanbield contained linux-yocto recipes for both 6.1 and 6.5 so it
was best to simply have these MACHINEs use linux-yocto-dev. Post-nanbield
oecore master only has a recipe for 6.6 (so far), therefore these two
MACHINEs can use linux-yocto by default, instead of linux-yocto-dev.

In order to boot successfully, most Rockchip SoCs require a specific
partitioning scheme which was defined many years (and many SoCs) ago. That
partitioning scheme places the SPL and U-Boot at specific offsets at the
start of the boot block device:
https://opensource.rock-chips.com/wiki_Partitions
The Rockchip partitioning scheme goes on to also define the locations
of a number of additional partitions, including the "boot" and "root"
partitions.
Since both the SPL and U-Boot have already been placed on the block device,
the "boot" partition only contains the extlinux config file and the
kernel+dtb/fitImage; it doesn't contain any bootloader artifacts (other
than the extlinux config).
The location of the SPL partition is a hard dependency since the BOOTROM
etched inside the Rockchip SoCs is programmed to load and run a validated
binary it finds at this location. The locations of the "boot" and "root"
partitions are not so rigid since it is U-Boot which interacts with them.
U-Boot is very flexible with how it finds boot components, and in its
support for various devices, filesystems, sizes, etc.
Both oe-core's U-Boot metadata and wic's bootimg-partition script contain
logic to generate the extlinux pieces required for a bootloader to boot
a Linux system. If both are enabled, the wic pieces silently clobber the
U-Boot pieces. However, the mechanisms contained in the U-Boot metadata are
much more flexible, from a user's point of view, than the mechanisms in
wic's bootimg-partition.
If a user wishes to setup some sort of A/B redundant update mechanism, they
must have redundant root partitions (in order to update their filesystem
contents) but they also need to have redundant boot partitions if they
wish to update the kernel as part of their update mechanism. Pairing
redundant kernel partitions with redundant filesystem partitions becomes
unnecessarily complicated. Therefore it makes sense to combine the kernel
and the filesystem into the same partition so that both the kernel and
filesystem are updated, or rolled back, in lock-step as one unit. Specific
kernel versions and configurations often have dependencies on user-space
components and versions.
The /boot location is not going away. This patch simply transfers
responsibility for its creation to the more flexible U-Boot mechanism
and includes the kernel as part of the same partition as the root
filesystem. Not only does it add flexibility, it also makes update schemes
more straightforward. Although having a separate /boot partition is a
"requirement" of the Rockchip partitioning scheme, it is not an actual
hard requirement when using a flexible, open-source bootloader (such as
U-Boot) instead of using Rockchip's proprietary miniloader, preloader, and
trust.img.
Build-tested for all boards.

ROCK Pi S is a Rockchip RK3308 based SBC from Radxa. It contains a 64-bit
quad core processor, USB, ethernet, wireless connectivity, and voice
detection engine in 1.7-inches square. The ROCK Pi S comes in two RAM sizes
256MB or 512MB DDR3, and uses an sdmmc card for OS and storage. Optionally,
some versions of the ROCK Pi S provide on-board storage via 1Gb/2Gb/4Gb/8Gb
of SLC NAND flash.
"S" stands for "small square" since the total board size of the rock-pi-s
is 1.7-inches square.
This BSP assumes booting from sdmmc, and using ttyS0 for the serial console
(similar to Raspberry Pi).
The latest version of the binary ddr initializer code from rkbin does not
provide a uart0 option, therefore all diagnostic output from rkbin and u-boot
is lost on the console (and replaced with a stream of gibberish until the
Linux kernel starts). Therefore, by default, the build assumes the user would
prefer to see this information and have the option to interact with U-Boot,
which means an older version of rkbin is used. The user can override this
decision by setting:

to add it explicitly.

Add support for the Radxa Rock 5B
https://wiki.radxa.com/Rock5/5b
The device-tree for this board is better in the 6.5 (and later) kernels,
therefore set the kernel to linux-yocto-dev for now (eventually this won't be
needed as linux-yocto moves forward).
Unfortunately the TF-A project does not currently have support for
the rk3588. Therefore, for the time-being, the only way to supply a
TPL/DDR-init for the rk3588 is to use the closed-source rkbin binaries
from Rockchip. If/when TF-A adds support for the rk3588 we can investigate
switching.
The rk3588 comes in two variants: rk3588 and rk3588s. The "s" option is a
stripped-down version of the rk3588. In the Linux kernel these two SoCs are
kept separate, with the rk3588 building on the rk3588s, so we've mimicked that
same behaviour here.

Remove the non-rockchip architectures from the kernel build since these are
all a waste of build time, filesystem space, and runtime memory.
