We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

Introduction ============ The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip RK3399 in a Qseven-compatible form-factor. RK3399-Q7 features: * CPU: ARMv8 64bit Big-Little architecture, * Big: dual-core Cortex-A72 * Little: quad-core Cortex-A53 * IRAM: 200KB * DRAM: 4GB-128MB dual-channel * eMMC: onboard eMMC * SD/MMC * GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY * USB: * USB3.0 dual role port * 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub * Display: HDMI/eDP/MIPI * Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF) * NOR Flash: onboard SPI NOR * Companion Controller: onboard additional Cortex-M0 microcontroller * RTC * fan controller * CAN Here is the step-by-step to boot to U-Boot on rk3399. Get the Source and build ATF/Cortex-M0 binaries =============================================== > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git Compile the ATF =============== > cd arm-trusted-firmware > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31 > cp build/rk3399/release/bl31.bin ../u-boot/bl31-rk3399.bin Compile the M0 firmware ======================= > cd ../rk3399-cortex-m0 > make CROSS_COMPILE=arm-cortex_m0-eabi- > cp rk3399m0.bin ../u-boot Compile the U-Boot ================== > cd ../u-boot > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all Package the image ================= > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl.img > make CROSS_COMPILE=aarch64-linux-gnu- u-boot.itb Flash the image =============== Copy the SPL to offset 32k and the FIT image containing the payloads (U-Boot proper, ATF, M0 Firmware, devicetree) to offset 256k on a SD card. > dd if=spl.img of=/dev/sdb seek=64 > dd if=u-boot.itb of=/dev/sdb seek=512 After powering up the board (with the inserted SD card), you should see a U-Boot console on UART0 (115200n8).
