[U-Boot] hardware versions to Kernel

I have an ARM CPU on a board that has 3 optional sub boards plugged into it, all of which have 3 hardware rev bits connected to the CPU Rather than getting the CPU to do mmap type stuff or sys/class/gpio stuff to read those versions in the kernel, is there a way for u-boot to push that
