+U-Boot for Powkiddy X55 Handheld Gaming Console
+===============================================
+
+This allows U-Boot to boot the Powkiddy X55 handheld gaming console.
+The X55 is very similar to the other existing Powkiddy RK3566 based
+devices, except that ADC channels 0-3 are used for the ADC joysticks.
+As a result the same auto detection functionality cannot be used on
+this device as the others.
+
+The indicator LED will change color based on the boot stage. Red means
+the device is powered on but has yet to start U-Boot, amber means the
+device has started U-Boot and is waiting to boot Linux, and when Linux
+has taken over the LED should change to green (or however it has been
+configured by the user).
+
+In the event the device needs to enter Rockchip download mode, a user
+can, starting with the power off, hold the left joystick all the way
+to the left and then power on the device. At this point the USB-C port
+marked DC/OTG should be set to peripheral mode and allow a user to
+manipulate the device with the rkdeveloptool tool.
+
+Building U-Boot
+---------------
+
+.. code-block:: bash
+
+ $ export CROSS_COMPILE=aarch64-linux-gnu-
+ $ export BL31=../rkbin/bin/rk35/rk3568_bl31_v1.34.elf
+ $ export ROCKCHIP_TPL=../rkbin/bin/rk35/rk3568_ddr_1056MHz_v1.13.bin
+ $ make powkiddy-x55-rk3566_defconfig
+ $ make
+
+This will build ``u-boot-rockchip.bin`` which can be written to an SD
+card.
+
+Image installation
+------------------
+
+Write the ``u-boot-rockchip.bin`` to an SD card or the internal eMMC
+offset 32kb from the start.
+
+.. code-block:: bash
+
+ $ dd if=u-boot-rockchip.bin of=/dev/mmcblk0 bs=512 seek=64
