2 Current Version : 00.00.03.05
3 Older Version   : 00.00.03.04

i.	PCI_DEVICE macro used

	Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.

		- Henrik Kretzschmar <henne@nachtwindheim.de>
ii.	All compiler warnings removed
iii.	megasas_ctrl_info struct reverted to 3.02 release
iv.	Default value of megasas_dbg_lvl set to 0
v.	Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of
	cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
	Eric Sesterhenn

2 Current Version : 00.00.03.04
3 Older Version   : 00.00.03.03

i.	Added Reboot notify
ii.	Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
	as Max Cmds FW can support

1 Release Date    : Tue Aug 22 16:33:14 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>
2 Current Version : 00.00.03.03
3 Older Version   : 00.00.03.02

i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
	New varible added to set dbg level.
ii.	Disable interrupt made as fn pointer as they are different for 1068 / 1078
iii.	Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
	3 SGE for 32 bit SGL
iv.	Tasklet added for cmd completion
v.	If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READY. This is used to do soft reset.
vi.	megasas_ctrl_prop structure updated (based on FW struct)
vii.	Added print : FW now in Ready State during initialization

2 Current Version : 00.00.03.02
3 Older Version   : 00.00.03.01

i.	Added FW tranistion state for Hotplug scenario

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.	Remove superflous instance_lock

	gets rid of the otherwise superflous instance_lock and avoids an unsave 
	unsynchronized access in the error handler.

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.

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."

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.

1 Release Date    : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com>
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"
