OvmfPkg/Qemu: Fix various typos Fix various typos in comments and documentation. When "VbeShim.asm" is modified, we have to re-run "VbeShim.sh" to update "VbeShim.h". The string modified by this patch is only used when the DEBUG macro (at the top of the file) is commented out. Since the string is not referenced, NASM eliminates it, resulting in the same byte array content in "VbeShim.h".

OvmfPkg/QemuFlashFvbServicesRuntimeDxe: list "FwBlockService.h" in INFs Among other things, the header file provides (extern) declarations for the EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL member functions that are defined in "FwBlockService.c". This way "mFvbDeviceTemplate.FwVolBlockInstance" can be initialized near the top of "FwBlockService.c", ahead of the member function definitions. "FwBlockService.c" is linked into both the DXE_SMM_DRIVER and the DXE_RUNTIME_DRIVER builds of this module, thus list the header file in both INF files.

OvmfPkg/QemuFlashFvbServicesRuntimeDxe: Clear C-bit when SEV is active Commit:24e4ad7 (OvmfPkg: Add AmdSevDxe driver) added a driver which runs early in DXE phase and clears the C-bit from NonExistent entry -- which is later split and accommodate the flash MMIO. When SMM is enabled, we build two sets of page tables; first page table is used when executing code in non SMM mode (SMM-less-pgtable) and second page table is used when we are executing code in SMM mode (SMM-pgtable). During boot time, AmdSevDxe driver clears the C-bit from the SMM-less-pgtable. But when SMM is enabled, Qemu Flash services are used from SMM mode. In this patch we explicitly clear the C-bit from Qemu flash MMIO range before we probe the flash. When OVMF is built with SMM_REQUIRE then call to initialize the flash services happen after the SMM-pgtable is created and processor has served the first SMI. At this time we will have access to the SMM-pgtable.

OvmfPkg: QemuFlashFvbServicesRuntimeDxe: adhere to -D SMM_REQUIRE When the user requires "security" by passing -D SMM_REQUIRE, and consequently by setting PcdSmmSmramRequire, enforce flash-based variables. Furthermore, add two ASSERT()s to catch if the wrong module were pulled into the build.
