Instead of letting the compiler error out if CONFIG_ENV_IS_NOWHERE is not selected by the user, let's just enforce it when the user builds for Puma RK3399 so that no check needs to be performed by the compiler and the configuration is always valid.

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 binary =================================== > git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git Compile the ATF =============== > cd trusted-firmware-a > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31 > cp build/rk3399/release/bl31/bl31.elf ../u-boot/bl31.elf Compile the U-Boot ================== > cd ../u-boot > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all Flash the image =============== Copy u-boot-rockchip.bin to offset 32k for SD/eMMC. Copy u-boot-rockchip-spi.bin to offset 0 for NOR-flash.
