[SCSI] mvsas: add support for 94xx; layout change; bug fixes
This version contains following main changes - Switch to new layout to support more types of ASIC. - SSP TMF supported and related Error Handing enhanced. - Support flash feature with delay 2*HZ when PHY changed. - Support Marvell 94xx series ASIC for 6G SAS/SATA, which has 2 88SE64xx chips but any different register description. - Support SPI flash for HBA-related configuration info. - Other patch enhanced from kernel side such as increasing PHY type [jejb: fold back in DMA_BIT_MASK changes] Signed-off-by: Ying Chu <jasonchu@marvell.com> Signed-off-by: Andy Yan <ayan@marvell.com> Signed-off-by: Ke Wei <kewei@marvell.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
