From 94cd65ddf4d70b1d536178d096eeb4d3bd08272e Mon Sep 17 00:00:00 2001 From: "Sumit.Saxena@lsi.com" Date: Fri, 6 Sep 2013 15:50:52 +0530 Subject: [SCSI] megaraid_sas: addded support for big endian architecture 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.
