Laszlo Ersek 6a7cba79b7 OvmfPkg: implement LockBoxLib
The S3 suspend/resume infrastructure depends on the LockBox library class.
The edk2 tree currently contains Null and SMM instances. The Null instance
is useless, and the SMM instance would require SMM emulation by including
the SMM core and adding several new drivers, which is deemed too complex.

Hence add a simple LockBoxLib instance for OVMF.

jordan.l.justen@intel.com:
 * use PCDs instead of EmuNvramLib
   - clear memory in PlatformPei on non S3 boots
 * allocate NVS memory and store a pointer to that memory
   - reduces memory use at fixed locations

Jordan Justen 74e5c15842 OvmfPkg/PlatformPei: Allocate PEI FV as ACPI NVS if S3 is supported
On S3 resume, we skip decompression of the PEI FV, and expect
to jump directly into it. For this to work, we need the OS to
leave the memory range untouched.

Laszlo Ersek 78a38b73c3 OvmfPkg: PlatformPei: reserve early page tables on X64
On X64, the reset vector code in
"OvmfPkg/ResetVector/Ia32/PageTables64.asm" identity maps the first 4GB of
RAM for PEI, consuming six frames starting at 8MB.

This range is declared by the PcdOvmfSecPageTablesBase/Size PCDs.

Jordan Justen 8e54500fd4 OvmfPkg: Add section of memory to use for PEI on S3 resume
This 32k section of RAM will be declared to the PEI Core on
S3 resume to allow memory allocations during S3 resume PEI.

If the boot mode is BOOT_ON_S3_RESUME, then we publish
the pre-reserved PcdS3AcpiReservedMemory range to PEI.

If the boot mode is not BOOT_ON_S3_RESUME, then we reserve
this range as ACPI NVS so the OS will not use it.

* Remove MAINFV
* Add PEIFV and DXEFV into FVMAIN_COMPACT
   - They are added as 2 sections of a file, and compressed
     together so they should retain good compression
* PcdOvmf(Pei|Dxe)MemFv(Base|Size) are set

   - Copy them separately to their memory locations.

Laszlo Ersek 9edb2933ab OvmfPkg/PlatformPei: emulated NV storage must be EfiRuntimeServicesData
SVN r14770 ("OvmfPkg/PlatformPei: correctly align emulated NV storage")
made sure the emulated NV storage was allocated with correct alignment.

However, the AllocateRuntimePool() -> AllocateAlignedPages() change
flipped the memory type from EfiRuntimeServicesData to
EfiBootServicesData. This causes variable services to access freed storage
at runtime. It crashes Windows 2008 R2 early at boot, for example.

Keep the alignment, but restore the memory type to EfiRuntimeServicesData,
by calling AllocateAlignedRuntimePages().

These helper functions are implemeted and documented in
"MdePkg/Library/PeiMemoryAllocationLib/MemoryAllocationLib.c".

jljusten 931a0c74ed OvmfPkg: enable PIIX4 IO space in the PEI phase
I. There are at least three locations in OvmfPkg that manipulate the PMBA
and related PIIX4 registers.

1. MiscInitialization() [OvmfPkg/PlatformPei/Platform.c]
   module type: PEIM -- Pre-EFI Initialization Module
   (a) currently sets the PMBA only: 00.01.3 / 0x40 bits [15:6]

2. AcpiTimerLibConstructor() [OvmfPkg/Library/AcpiTimerLib/AcpiTimerLib.c]
   module type: BASE -- probably callable anywhere after PEI
   (a) sets the PMBA if needed:      00.01.3 / 0x40 bits [15:6]
   (b) sets PCICMD/IOSE if needed:   00.01.3 / 0x04 bit  0
   (c) sets PMREGMISC/PMIOSE:        00.01.3 / 0x80 bit  0

3. AcpiInitialization() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
   module type: DXE_DRIVER -- Driver eXecution Environment
   (a) sets SCI_EN, which depends on correct PMBA setting from earlier

(
  The relative order of #1 and #3 is dictated minimally by their module
  types. Said relative order can be verified with the boot log:

       27 Loading PEIM at 0x00000822320 EntryPoint=0x00000822580
          PlatformPei.efi
       28 Platform PEIM Loaded
     1259 PlatformBdsInit
     1270 PlatformBdsPolicyBehavior

  Line 28 is printed by InitializePlatform()
  [OvmfPkg/PlatformPei/Platform.c] which is the entry point of that
  module. The other two lines are printed by the corresponding functions
  in "OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c".
)

Currently #2 (AcpiTimerLibConstructor()) is called in a random spot
(whenever it gets loaded from the firmware image) and masks the
insufficient setup in #1. We shouldn't depend on that, PEI should finish
with IO space being fully accessibe. In addition, PEI should program the
same PMBA value as AcpiTimerLib.

II. The PEI change notwithstanding, AcpiTimerLib should stay defensive and
ensure proper PM configuration for itself (either by confirming or by
doing).

III. Considering a possible cleanup/unification of #2 and #3: timer
functions relying on AcpiTimerLibConstructor(),

- MicroSecondDelay()
- NanoSecondDelay()
- GetPerformanceCounter()
- GetPerformanceCounterProperties()
- GetTimeInNanoSecond()

may be called before #3 is reached (in Boot Device Selection phase), so we
should not move the initialization from #2 to #3. (Again, AcpiTimerLib
should contain its own setup.)

We should also not move #3 to an earlier phase -- SCI_EN is premature
unless we're about to boot real soon ("enable generation of SCI upon
assertion of PWRBTN_STS, LID_STS, THRM_STS, or GPI_STS bits").
