2013-09-10[SCSI] megaraid_sas: addded support for big endian architectureSumit.Saxena@lsi.com
This patch will add big endian architecture support to megaraid_sas driver. The support added is for LSI MegaRAID all generation controllers- (3Gb/s, 6Gb/s and 12 Gb/s controllers). We have done basic sanity test @ppc64 arch and @x86_64. Additional testing/observations are welcome.

2013-06-24[SCSI] megaraid_sas: Add support for Uneven Span PRL11Sumit.Saxena@lsi.com
MegaRAID older Firmware does not support uneven span configuration for PRL11. E.g User wants to create 34 Driver PRL11 config, it was not possible using old firmware, since it was not supported configuration in old firmware Old Firmware expect even number of Drives in each span and same number of physical drives at each span. Considering above design, 17 Drives at Span-0 and 17 drives at span-1 was not possible. Now, using this new feature Firmware and Driver both required changes. New Firmware can allow user to create 16 Drives at span-0 and 18 Drives at span-1. This will allow user to create 34 Drives Uneven span PRL11. RAID map is interface between Driver and FW to fetch all required fields(attributes) for each Virtual Drives. Since legacy RAID map consider Even Span design, there was no place to keep Uneven span information in existing Raid map. Because of this limitation, for Uneven span VD, driver can not use RAID map. This patch address the changes required in Driver to support Uneven span PRL11 support. 1. Driver will find if Firmware has UnevenSpanSupport or not by reading Controller Info. 2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its capability of handling UnevenSpan PRL11 to the firmware. 3. Driver will update its copy of span info on each time Raid map update is called. 4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver uses Span Set info to find relavent fields for that particular Virtual Disk) More verbose prints will be available by setting "SPAN_DEBUG" to 1 at compilation time.

2013-02-22[SCSI] megaraid_sas: Dont load DevHandle unless FastPath enabledadam radford
The following patch for megaraid_sas will fix an issue where the driver should not be loading the DevHandle unless FastPath is enabled. If FastPath was not enabled, this means the hardware raid map validation failed for some reason, or the map was corrupted, which could mean the DevHandle could be invalid.
