[PATCH 11/15] hisi_sas: fix HBA SAS addr endianness for v1 hw
From: John Garry
Date: Tue Sep 06 2016 - 11:28:41 EST
The endianness for the SAS address in the TX_ID_DWORD
registers is set incorrectly.
We see errors like this in the boot log for v2 hw (which would
have the same issue as v1 hw):
[ 7.583284] sas: target proto 0x0 at 50000d1108e7923f:0x1f not handled
This is due to the host SAS addr not matching the PHY SAS
addr in the expander host-attached phy discovery responses.
To fix, we byte swap the SAS addr from BE to LE (which is
the endianness of the SAS controller).
