[PATCH 1/5] mvsas : redesign the mvsas driver architecture.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We redesign the mvsas driver architecture. Then the driver can support Marvell's
64 bit PCIE-X SAS/SATA 3Gb/s mv64xx chip and 6Gb/s mv94xx chip based host
adapters. I created a directory for the driver in scsi folder and delete the
original simple driver.

modify Kconfig entry for the mvsas driver, and change the driver path.
