UEFI boot support for locked SEDs updated

Eric Dong of Intel has updated UEFI’s TCG OVAL support, used with SEDs, how the UEFI-based system will work with the locked SEDs, when the user has no valid password:

[Patch] SecurityPkg OpalPasswordDxe: Enhance input password process.

Enhance the input password process, when device in unlock status and user press ESC, shutdown the device. If user reach the max try number, shutdown the device.

+  L”Confirm: Not unlock device and continue boot?.”,
+  L”Press ENTER to confirm, Press Esc to input password”,
+  L”Warning: system in unkown status, must shutdown!”,
+  L”Press ENTER to shutdown.”,

– L”Opal password retry count is expired. Keep lock and continue boot.”,
+ L”Opal password retry count exceeds the limit. Must shutdown!”,
  L”Press ENTER to continue”,
