Subject: [PATCH 6/9] [SCSI] mvsas: Add new macros and functions
From: Xiangliang Yu <yuxiangl@...vell.com>
-- Add new macros: MVS_SOFT_RESET, MVS_HARD_RESET, MVS_PHY_TUNE,
MVS_COMMAND_ACTIVE, EXP_BRCT_CHG, MVS_MAX_SG
-- Add new member sg_width in struct mvs_chip_info
-- Use macros rather than magic number
-- Add new functions: mvs_fill_ssp_resp_iu, mvs_set_sense,
mvs_94xx_clear_srs_irq, mvs_94xx_phy_set_link_rate
Signed-off-by: Xiangliang Yu <yuxiangl@...vell.com>
