This patchset introduces support for the HiSi SAS v2 hw.For the entire series:
The major difference between v1 and v2 hw is support
for SATA/STP.
Known limitation:
- We cannot connect a SATA disk through a 12G expander
without disabling the STP buffer. Direcly connecting
a SATA disk to the HBA is ok.
