Mike Smith d5a51e03e7 This is a driver for the AMI MegaRAID family of controllers. It all of
the AMI PCI controllers using the 8LD firmware interface (40LD firmware
will be supported as soon as I have hardware to test with).

These controllers are rebadged by Dell as the PERC, as well as by HP
and possibly other vendors.
