The boot (and fallback/emergency boot) concept for the RK3399-Q7 differs from Rockchip's reference platforms.
On the RK3399-Q7, some of this functionality is present in the bootloader itself (and configurable); some is backed in hardware by the Qseven BIOS_DISABLE signal to invoke the final stages of fallbacks (i.e. either an external boot bypassing on-module memories or falling back to the BROM for USB recovery). In summary: the ADC-based boot_mode check does not apply for the RK3399-Q7 and we therefore disable it (in this commit) by setting CONFIG_BOOT_MODE_REG to 0.
