To cover additional host controller programming mentioned in the UFS
specification we have added an additional protocol
that allows the UEFI driver to give control to platform driver. This allows the
platform to perform any additional
steps needed for the stable operation.
Changes in v2:
- UFS driver will abort initializaton when it fails to get host controler
information
- Fixed bug with calling post link startup callback on failed device detection
Test coverage:
Tested on platform with UFS 2.1 host controller with Samsung UFS2.0 part with 3
LUs enabled All LUs have been enumerated in boot manager.
Tested that enumeration works without platform protocol installed(on host
controller that can support it) Tested that enumeration works with platform
protocol installed and with additional programming steps after link
startup(power mode change to GEAR2).
