1 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com>
2 Current Version : 00.00.02.04
3 Older Version : 00.00.02.04
i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added.
During initialization, depending on the device id, the template members
are initialized with function pointers specific to the ppc or
xscale controllers.

<Sumant.Patro@lsil.com>
2 Current Version : 00.00.02.04
3 Older Version : 00.00.02.02
i. Register 16 byte CDB capability with scsi midlayer
"Ths patch properly registers the 16 byte command length capability of the
megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
hardware supports 16 byte CDB's."
