Nope, CONFIG_COMMON_CLK_ZYNQMP=y does not help. Maybe the defconfig is
missing even more. If you have some reference, I'm happy to try. I
suspect that earlyprintk will also not reveal more without clocks (but I
didn't play with that yet).
Meanwhile, I'm carrying a revert of this commit and a related cleanup.
That helps for now.
