+
+Here is the step-by-step to boot to U-Boot on SOM-RK3588-Q7 Tiger from Theobroma
+Systems.
+
+Get the TF-A and DDR init (TPL) binaries
+----------------------------------------
+
+.. prompt:: bash
+
+ git clone https://github.com/rockchip-linux/rkbin
+ cd rkbin
+ export RKBIN=$(pwd)
+ export BL31=$RKBIN/bin/rk35/rk3588_bl31_v1.38.elf
+ export ROCKCHIP_TPL=$RKBIN/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.11.bin
+ sed -i 's/^uart baudrate=.*$/uart baudrate=115200/' tools/ddrbin_param.txt
+ sed -i 's/^uart iomux=.*$/uart iomux=2/' tools/ddrbin_param.txt

+ ./tools/boot_merger RKBOOT/RK3588MINIALL.ini
+ export RKDB=$RKBIN/rk3588_spl_loader_v1.11.112.bin
+
+This will setup all required external dependencies for compiling U-Boot. This will
+be updated in the future once upstream Trusted-Firmware-A supports RK3588 or U-Boot
+gains support for open-source DRAM initialization in TPL.
+
+Build U-Boot
+------------
+
+.. prompt:: bash
+
+ cd ../u-boot
+ make CROSS_COMPILE=aarch64-linux-gnu- tiger-rk3588_defconfig all
+
+This will build ``u-boot-rockchip.bin`` which can be written to an MMC device
+(eMMC or SD card).
+
+Flash the image
+---------------
+
+Copy ``u-boot-rockchip.bin`` to offset 32k for SD/eMMC.
+
+SD-Card
+~~~~~~~
+
+.. prompt:: bash
+
+ dd if=u-boot-rockchip.bin of=/dev/sdX seek=64
+
+.. note::
+
+ Replace ``/dev/sdX`` to match your SD card kernel device.
+
+eMMC
+~~~~
+
+``rkdeveloptool`` allows to flash the on-board eMMC via the USB OTG interface
+with help of the Rockchip loader binary.
+
+To enter the USB flashing mode on Haikou baseboard, remove any SD card, insert a
+micro-USB cable in the ``Q7 USB P1`` connector (P8), move ``SW5`` switch into
+``BIOS Disable`` mode, power cycle or reset the board and move ``SW5`` switch
+back to ``Normal Boot`` mode. A new USB device should have appeared on your PC
+(check with ``lsusb -d 2207:350b``).
+
+To flash U-Boot on the eMMC with ``rkdeveloptool``:
+
+.. prompt:: bash
+
+ git clone https://github.com/rockchip-linux/rkdeveloptool
+ cd rkdeveloptool
+ autoreconf -i && CPPFLAGS=-Wno-format-truncation ./configure && make
+ ./rkdeveloptool db "$RKDB"
