OvmfPkg: Fix dependency issue when StandaloneMm enabled
When enabled support of StandaloneMm on OVMF, ovmf boot manager depends
on S3SaveStateDxe. However, the support of StandaloneMm currently
doesn't include that driver. This causes assertion on ovmf with DEBUG
and exception on RELEASE.
PlatformBootManagerLib requires S3SaveStateDxe which produces
EFI_S3_SAVE_STATE_PROTOCOL to successfully able to store boot secript.
Given the commit b017b1b that introduced didn't indicate any potential
issue. Also enabling that library, there is no other issues observed.
S3SaveStateDxe should always be built with OVMF whether StandaloneMm is
enabled or not.
Observations:
OVMF DEBUG build has been observed to trigger this assertions:
ASSERT_EFI_ERROR (Status = Not Found)
ASSERT BdsPlatform.c(1583): !(((RETURN_STATUS)(Status)) >=
0x8000000000000000ULL)
On OVMF RELEASE build due missing null check BootScript is dereferenced
while it is NULL. Which caused following exception:
