REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409 For the current implementation of OpalPassword drivers, it has a feature to support devices being automatically unlocked in the S3 resume. For this feature, two types of devices are supported: * ATA hard disks working under AHCI mode * NVM Express devices The support of this feature requires the above 2 types of device to be initialized at the PEI phase during S3 resume, which is done by the co-work of the OpalPasswordDxe driver and the OpalPasswordPei driver. More specifically, the OpalPasswordDxe will handle: * Pre-allocate MMIO resource and save it in a driver internal LockBox for OpalPasswordPei to retrieve; * Save the PCI configuration space of ATA controllers into boot script. Meanwhile, the OpalPasswordPei will handle: * Rely on the boot script for the PCI configuration space program of ATA controllers; * Restore the driver internal LockBox to get the MMIO resource; * Complete the PCI configuration space program for ATA and NVME controllers; * Initialize ATA and NVME controllers and devices. This commit will remove these hardware initialization related codes from the OpalPassword drivers. The hardware initialization will be covered by PEI storage device drivers (e.g. NvmExpressPei & AhciPei in the MdeModulePkg). After such codes removal, the OpalPasswordDxe will only handle: * Construct/update the S3StorageDeviceInitList LockBox with the managing ATA and NVME devices. And the OpalPasswordPei will only handle: * Locate Storage Security Command PPI instances to perform the device automatic unlock during the S3 resume.
