That one didn't help unfortunately. u-boot still prints "SATA link 0 
timeout". Booting kernel 5.7.0-0.bpo.2-arm64 with that and sata works, 
but booting 4.19.0-10-arm64 and it doesn't: "ata1: SATA link down 
(SStatus 131 SControl 300)" is printed all over again.

Heh, nice. That indeed works!

Well minus one thing, see my reply to "arm: mvebu: Espressobin: Define 
console env".

Thanks,
