rock3a v1.31 doesn't boot

[flatmax]

Not sure why, but this system works for the rock3a v1.3. It doesn't seem to boot for the rock3a v1.31

Kernel and Uboot changes were developed on 1.31 so not sure how this is possible, haven't seen Radxa documentation on differences between 1.3 and 1.31, will reach out to their support.
