Add board-specific devicetree/config for the RK3399T-based Radxa ROCK 4SE
board. This board offers similar peripherals in a similar form-factor to
the existing ROCK Pi 4B but uses the cost-optimised RK3399T processor
(which has different OPP table than the RK3399) and other minimal hardware

6cf6fe2537 board: rockchip: add Anbernic RGXX3 Series Devices
The Anbernic RGxx3 is a "pseudo-device" that encompasses the following
devices:

 - Anbernic RG353M
 - Anbernic RG353P
 - Anbernic RG353V
 - Anbernic RG353VS
 - Anbernic RG503

The rk3566-anbernic-rgxx3.dtsi is synced with upstream Linux, but
rk3566-anbernic-rgxx3.dts is a U-Boot specific devicetree that
is used for all RGxx3 devices.

Via the board.c file, the bootloader automatically sets the correct
fdtfile, board, and board_name environment variables so that the
correct devicetree can be passed to Linux. It is also possible to
simply hard-code a single devicetree in the boot.scr file and use
that to load Linux as well.

The common specifications for each device are:

 - Rockchip RK3566 SoC
 - 2 external SDMMC slots
 - 1 USB-C host port, 1 USB-C peripheral port
 - 1 mini-HDMI output
 - MIPI-DSI based display panel
 - ADC controlled joysticks with a GPIO mux
 - GPIO buttons
 - A PWM controlled vibrator
 - An ADC controlled button

All of the common features are defined in the devicetree synced from
upstream Linux.

TODO: DSI panel auto-detection for the RG353 devices (requires porting
of DSI controller driver and DSI-DPHY driver to send DSI commands to
the panel).

4773e9d5ed rockchip: Use an external TPL binary on RK3568
Rockchip SoCs typically use U-Boot TPL to initialize DRAM, then jumps
back to BootRom to load next stage, U-Boot SPL, into DRAM. BootRom then
jumps to U-Boot SPL to continue the normal boot flow.

However, there is no support to initialize DRAM on RK35xx SoCs using
U-Boot TPL and instead an external TPL binary must be used to generate a
bootable u-boot-rockchip.bin image.

Add CONFIG_ROCKCHIP_EXTERNAL_TPL to indicate that an external TPL should
be used. Build U-Boot with ROCKCHIP_TPL=/path/to/ddr.bin to generate a
bootable u-boot-rockchip.bin image for RK3568.

6d36e92d28 rockchip: rk3399: Add support for chromebook_kevin
Add support for Kevin, an RK3399-based convertible chromebook that is
very similar to Bob. This patch is mostly based on existing support for
Bob, with only minor changes for Kevin-specific things.

Unlike other Gru boards, coreboot sets Kevin's center logic to 925 mV,
so adjust it here in the dts as well. The rk3399-gru-kevin devicetree
has an unknown event code reference which has to be defined, set it
to the Linux counterpart. The new defconfig is copied from Bob with the
diffconfig:

     DEFAULT_DEVICE_TREE "rk3399-gru-bob" -> "rk3399-gru-kevin"
     DEFAULT_FDT_FILE "rockchip/rk3399-gru-bob.dtb" -> "rockchip/rk3399-gru-kevin.dtb"
     VIDEO_ROCKCHIP_MAX_XRES 1280 -> 2400
     VIDEO_ROCKCHIP_MAX_YRES 800 -> 1600
    +TARGET_CHROMEBOOK_KEVIN y

With this Kevin can boot from SPI flash to a usable U-Boot prompt on the
display with the keyboard working, but cannot boot into Linux for
unknown reasons.

eMMC starts in a working state but fails to re-init, microSD card works
but at a lower-than-expected speed, USB works but causes a hang on
de-init. There are known workarounds to solve eMMC and USB issues.

As an additional step to move documentation to doc/boards/rockchip
improve format of the supported board list to make it more readable.
Additionally, add the configuration files used to build them based on
doc/README.rockchip.

338b86c9b3 doc: boards: Add rockchip documentation
Rockchip has documentation file, doc/README.rockchip but
which is not so readable to add or understand the existing
contents. Even the format that support is legacy readme
in U-Boot.

Add rockchip specific documentation file using new rst
format, which describes the information about Rockchip
supported boards and it's usage steps.

Added minimal information about rk3288, rk3328, rk3368
and rk3399 boards and usage. This would indeed updated
further based on the requirements and updates.
