Hello, Yuan.

Yeap, almost there, just few very minor things. :)

Why doesn't sb600 just use ahci_pmp_retry_srst_ops?

Heh, I know I suggested that name but that is one ugly name.  If
anyone has any better idea, please come forward.

srst equals softreset, so ahci_pmp_retry_softreset() should do.

Maybe it's better to place ahci_pmp_retry_srst_ops after ahci_ops?

It would be better if the name reflects that it's not for specific
workaround.

Thank you.
