I tested on sun8i-v40-bananapi-m2-berry (with an adapted device
tree).  I got it to work, but only if the U-Boot has support for AHCI
already (from the Banana Pi M2 Ultra support).  With an U-Boot that
hasn't, the system hangs at boot (probably when probing ahci-sunxi). 

Did you test this case on the M2 Ultra board?  (I think SATA should
work the same on both boards, but there may be subtle differences)

Perhaps I did not apply all necessary patches. I took this series and
your minor fixes series for ahci_platform.
