 Hi gonzo,

 Just tested this patch on rockpro64 and rock64 and this works for me.
 Whatever leads me to commit
https://svnweb.freebsd.org/base?view=revision&revision=335445 seems
fixed now ?
 In rk3399_set_delays you print rk3328 btw. And both printfs that shows
the delay should be under bootverbose.
 With that you can commit with Reviewed by: manu :)

 I don't think that it will help Charles but the code make sense and
matches the TRM.

 Thanks,
