Rockchip boards
---------------
Rockchip is a SoC solutions provider for tablets & PCs, streaming media
TV boxes, AI audio & vision, IoT hardware.
A wide range of Rockchip SoCs with associated boards are supported in
mainline U-Boot.

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. Cc: Marty E.

board: rockchip: Add Edgeble Neural Compute Module 6 Neural Compute Module 6(Neu2) is a 96boards SoM-CB compute module based on Rockchip RK3588 from Edgeble AI. General features: - Rockchip RK3588 - up to 32GB LPDDR4x - up to 128GB eMMC - 2x MIPI CSI2 FPC On module WiFi6/BT5 is available in the following Neu6 variants. Neural Compute Module 6(Neu6) IO board is an industrial form factor ready-to-use IO board from Edgeble AI. IO board offers plenty of peripherals and connectivity options and this patch enables basic eMMC and UART which is enough to successfully boot Linux.

Building
--------
TF-A
^^^^
TF-A is required when building ARM64 Rockchip SoCs images.
To build TF-A:
.. code-block:: bash
git clone --depth 1 https://github.com/ARM-software/arm-trusted-firmware.git
cd arm-trusted-firmware
make realclean
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399
cd ..
Specify the PLAT= with desired Rockchip platform to build TF-A for.
U-Boot
^^^^^^
.. code-block:: bash
git clone --depth 1 https://source.denx.de/u-boot/u-boot.git
cd u-boot
To build px30 boards:
.. code-block:: bash
export BL31=../arm-trusted-firmware/build/px30/release/bl31/bl31.elf
make evb-px30_defconfig

To build rk3066 boards:
.. code-block:: bash

make CROSS_COMPILE=arm-linux-gnueabihf-
To build rk3288 boards:
.. code-block:: bash
make evb-rk3288_defconfig

To build rk3568 boards:
.. code-block:: bash
export BL31=../arm-trusted-firmware/build/rk3568/release/bl31/bl31.elf
[or]export BL31=../rkbin/bin/rk35/rk3568_bl31_v1.34.elf

Flashing
--------
1. Package the image with U-Boot TPL/SPL
-----------------------------------------
SD Card
^^^^^^^
All Rockchip platforms (except rk3128 which doesn't use SPL) are now
supporting a single boot image using binman and pad_cat.
To write an image that boots from a SD card (assumed to be /dev/sda):
.. code-block:: bash
sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
sync
eMMC
^^^^
eMMC flash would probe on mmc0 in most of the Rockchip platforms.
Create GPT partition layout as defined in $partitions:
.. code-block:: bash
mmc dev 0
gpt write mmc 0 $partitions
Connect the USB-OTG cable between the host and a target device.
Launch fastboot on the target with:
.. code-block:: bash
fastboot 0
Upon a successful gadget connection the host shows the USB device with:
.. code-block:: bash
lsusb
# Bus 001 Device 020: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode
Program the flash with:
.. code-block:: bash
sudo fastboot -i 0x2207 flash loader1 idbloader.img
sudo fastboot -i 0x2207 flash loader2 u-boot.itb
Note:
For Rockchip 32-bit platforms the U-Boot proper image
is u-boot-dtb.img
SPI
^^^
The SPI boot method requires the generation of idbloader.img with help of the mkimage tool.
SPL-alone SPI boot image:
.. code-block:: bash
./tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin idbloader.img
TPL+SPL SPI boot image:
.. code-block:: bash
./tools/mkimage -n rk3399 -T rkspi -d tpl/u-boot-tpl.bin:spl/u-boot-spl.bin idbloader.img
Copy SPI boot images into SD card and boot from SD:
.. code-block:: bash
sf probe
load mmc 1:1 $kernel_addr_r idbloader.img
sf erase 0 +$filesize
sf write $kernel_addr_r 0 ${filesize}
load mmc 1:1 ${kernel_addr_r} u-boot.itb
sf erase 0x60000 +$filesize
sf write $kernel_addr_r 0x60000 ${filesize}
2. Package the image with Rockchip miniloader
---------------------------------------------
Image package with Rockchip miniloader requires rkbin [1].
.. code-block:: bash
cd ..
git clone --depth 1 https://github.com/rockchip-linux/rkbin
Create idbloader.img:
.. code-block:: bash
cd u-boot
./tools/mkimage -n px30 -T rksd -d ../rkbin/bin/rk33/px30_ddr_333MHz_v1.16.bin idbloader.img
cat ../rkbin/bin/rk33/px30_miniloader_v1.31.bin >> idbloader.img
sudo dd if=idbloader.img of=/dev/sda seek=64
Create trust.img:
.. code-block:: bash
cd ../rkbin
./tools/trust_merger RKTRUST/PX30TRUST.ini
sudo dd if=trust.img of=/dev/sda seek=24576
Create uboot.img [2]:
.. code-block:: bash
cd ../u-boot
../rkbin/tools/loaderimage --pack --uboot u-boot-dtb.bin uboot.img 0x200000
sudo dd if=uboot.img of=/dev/sda seek=16384
Note:
1. rkbin binaries are regularly updated, so it would be recommended to use the latest version.
2. 0x200000 is a load address and is an option for some platforms.
3. Package the RK3066 image with U-Boot TPL/SPL on NAND
-------------------------------------------------------
Unlike later SoC models the rk3066 BootROM doesn't have SDMMC support.
If all other boot options fail then it enters into a BootROM mode on the USB OTG port.
This method loads TPL/SPL on NAND with U-Boot and kernel on SD card.
SD Card
^^^^^^^
U-Boot expects a GPT partition map and a boot directory structure with files on the SD card.
.. code-block:: none
Partition Map for MMC device 0 -- Partition Type: EFI
Part Start LBA End LBA Name
1 0x00000040 0x00001f7f "loader1"
2 0x00004000 0x00005fff "loader2"

Make sure boot and esp flag are set for the boot partition.
Loader1 partition is not used by RK3066.
Boot partition:

To write a U-Boot image to the SD card (assumed to be /dev/sda):
.. code-block:: bash
sudo dd if=u-boot-dtb.img of=/dev/sda seek=16384

Bring device in BootROM mode:
If bricked and no BootROM mode shows up then connect pin 8 and 9 of the NAND flash
with a needle while reconnecting to the USB OTG port to a PC.
Show connected devices with:
.. code-block:: bash

Create NAND image:
Size of SPL and TPL must be aligned to 2kb.
Program with commands in a bash script ./flash.sh:
