  gMarvellTokenSpaceGuid.PcdUtmiPhyRegUtmiUnit

Indicates base address of the UTMI unit.

  gMarvellTokenSpaceGuid.PcdUtmiPhyRegUsbCfg

Indicates address of USB Configuration register.

  gMarvellTokenSpaceGuid.PcdUtmiPhyRegUtmiCfg

Indicates address of external UTMI configuration.

  gMarvellTokenSpaceGuid.PcdUtmiPhyUtmiPort

Indicates type of the connected USB port.
