With our efuse driver for the RK3399 ready, we can add the board-specific code that consumes the cpuid from the efuse block and postprocesses it into the system serial (using the same CRC32 based derivation as in Linux).
We expose the cpuid via two distinct environment variables: serial# - the serial number, as derived in Linux cpuid# - the raw 16 byte CPU id field from the fuse block

But don't you want to use the same mechanism to make sure you get the right misc driver?
Applied to u-boot-rockchip, thanks!
