+GenBook
+=======
+Cool Pi GenBook is a laptop powered by RK3588, it works with a
+carrier board connect with CM5.
+
+Specification:
+* Rockchip RK3588
+* LPDDR5X 8/32 GB
+* eMMC 64 GB
+* SPI Nor 8 MB
+* HDMI Type A out x 1
+* USB 3.0 Host x 1
+* USB-C 3.0 with DisplayPort AltMode
+* PCIE M.2 E Key for RTL8852BE Wireless connection
+* PCIE M.2 M Key for NVME connection
+* eDP panel with 1920x1080
+
+Here is the step-by-step to compile and boot to U-Boot on GenBook.
+
+Get the TF-A and DDR init (TPL) binaries
+----------------------------------------
+
+.. prompt:: bash
+
+   > cd u-boot
+   > export ROCKCHIP_TPL=../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.17.bin
+   > export BL31=../rkbin/bin/rk35/rk3588_bl31_v1.46.elf
+   > make coolpi-genbook-cm5-rk3588_defconfig
+   > make CROSS_COMPILE=aarch64-linux-gnu-
+
+This will build ``u-boot-rockchip.bin`` for eMMC and ``u-boot-rockchip-spi.bin`` for SPI Nor.
+
+Write u-boot to eMMC or SPI Nor from a Linux system on the laptop
+-----------------------------------------------------------------
+
+Copy ``u-boot-rockchip.bin`` and ``u-boot-rockchip-spi.bin`` to the laptop.
+
+eMMC
+~~~~
+
+.. prompt:: bash
+
+   dd if=u-boot-rockchip.bin of=/dev/mmcblk0 bs=512 seek=64
+
+SPI Nor
+~~~~~~~
+
+.. prompt:: bash
+
+  dd if=u-boot-rockchip-spi.bin of=/dev/mtdblock0
+
+``upgrade_tool`` allows to flash the on-board SPI Nor via the USB TypeC interface
+with help of the Rockchip loader binary.
+
+To enter the USB flashing mode, connect the laptop and your HOST PC with a USB-C
+cable, reset the laptop with ``Loader Key`` pressed.
+On your PC, check with ``lsusb -d 2207:350b``).
+
+To flash U-Boot on the SPI Nor with ``upgrade_tool``:
+
+.. prompt:: bash
+
+  upgrade_tool db rk3588/MiniLoaderAll.bin
+  upgrade_tool ssd       // Input 5 for SPINOR download mode
+  upgrade_tool wl 0 u-boot-rockchip-spi.bin
+  upgrade_tool rd
