1 Release Date    : Sun May 14 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>
2 Current Version : 00.00.03.01
3 Older Version   : 00.00.02.04

i.	Added support for ZCR controller.

		New device id 0x413 added.

ii.	Bug fix : Disable controller interrupt before firing INIT cmd to FW.

		Interrupt is enabled after required initialization is over.
		This is done to ensure that driver is ready to handle interrupts when
		it is generated by the controller.

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.

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."

2 Current Version : 00.00.02.02
3 Older Version   : 00.00.02.01

i.	New template defined to represent each family of controllers (identified by processor used).
	The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

2 Current Version : 00.00.02.00-rc4
3 Older Version   : 00.00.02.01

i.	Code reorganized to remove code duplication in megasas_build_cmd.

	"There's a lot of duplicate code megasas_build_cmd.  Move that out of the different codepathes and merge the reminder of megasas_build_cmd into megasas_queue_command"

		- Christoph Hellwig <hch@lst.de>

ii.	Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.

	"MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"
