 You should have a working kernel with this: https://github.com/evadot/freebsd/tree/h3
 The code used to work before the clk bit were commited, I haven't tested since.
 This doesn't support SMP as I haven't looked at the cpu power clamp yet.

 And detailed on how you had uboot compiled could always be intersting :)
