This series addresses regression problems with
commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7 ahci: start engine only during soft/hard resets
Because the fix provided by the above commit caused COMRESET failures and 10 second boot-time/resume-time hangs for certain DVD drives, we need to make the fix conditional to certain devices/platforms. Add a flag for this.
Brian
v2: change flag name to AHCI_HFLAG_DELAY_ENGINE, write more detailed comments
v1: flag named AHCI_HFLAG_STRICT_SPEC
Brian Norris (3): ahci: add AHCI_HFLAG_DELAY_ENGINE host flag ahci: move AHCI_HFLAGS() macro to ahci.h ahci_platform: add STRICT_AHCI platform type
