From ae791c05694d7391ee9261a0450a50f7e95aedfd Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Sep 2007 13:14:12 +0900 Subject: libata-pmp-prep: implement ATA_LFLAG_NO_SRST, ASSUME_ATA and ASSUME_SEMB Some links on some PMPs locks up on SRST and/or report incorrect device signature. Implement ATA_LFLAG_NO_SRST, ASSUME_ATA and ASSUME_SEMB to handle these quirky links. NO_SRST makes EH avoid SRST. ASSUME_ATA and SEMB forces class code to ATA and SEMB_UNSUP respectively. Note that SEMB isn't currently supported yet so the _UNSUP variant is used.
