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

Brian Norris (3):

ahci: move AHCI_HFLAGS() macro to ahci.h
ahci_platform: add STRICT_AHCI platform type
