In V3, Use Odt to replace ODT, Cke to replace CKE, Id to replace ID,
and Cl to replace CL in structure field name.
In V2, separate DDR3, DDR4 and LPDDR definition into the different files;
use the different SPD prefix as structure definitions for each SPD type.

AP will get target C-State from eax[7:4]. We do shift in ebx firstly before set
to eax. It will lead ebx is incorrect in the next time.
The fix is to set ebx to eax firstly and does shift in eax. Thus, ebx could keep
original value.

For long mode DXE, we will disable paging on AP to protected mode to execute AP
safe loop code in reserved memory range under 4GB. But we forget to allocate
stack for AP under 4GB and AP still are using original AP stack. If original AP
stack is larger than 4GB, it cannot be used after AP is transferred to protected
mode. Besides MwaitSupport == TRUE, AP stack is still required during phase of
disabling paging in long mode DXE.
Moreover, even though AP stack is always under 4GB (a) in Ia32 DXE and (b) with
this patch, after transferring to protected mode from X64 DXE, AP stack
(in BootServiceData) maybe crashed by OS after Exit Boot Service event.
This fix is to allocate reserved memory range under 4GB together with AP safe
loop code. APs will switch to new stack in safe loop code.

The LinuxLoader application boots Linux in a way that prevents the OS
from accessing UEFI runtime services. Since we have better ways now
of invoking the kernel (via GRUB, or directly via the kernel's UEFI
stub), remove the obsolete LinuxLoader so that people will no longer
mistake it for a suitable reference of how to invoke the OS from UEFI.

According to AHCI Spec 1.3 GHC.AE bit description:
"The implementation of this bit is dependent upon the value of the
CAP.SAM bit. If CAP.SAM is '0', then GHC.AE shall be read-write and shall
have a reset value of '0'. If CAP.SAM is '1', then AE shall be read-only
and shall have a reset value of '1'."
Being in AhciMode, for proper operation it is required, that GHC.AE bit
is always set, before any other AHCI registers are written to. Current
AhciMode implementation, both in AhciReset() and AhciModeInitialization()
functions, set GHC.AE bit only depending on 'CAP.SAM == 0' condition,
assuming (according to the AHCI spec), that otherwise it has to be set
anyway. It may however happen, that even if 'CAP.SAM == 1', GHC.AE
requires updating by software.
This patch enables in AhciMode setting GHC.AE in case its initial value
is '0'. It fixes AHCI support for Marvell Armada 70x0 and 80x0 SoC
families. The change is transparent to all other platforms.

We send ADDRESS DEVICE CMD in XhcInitializeDeviceSlot(), which will
cause XHC issue a USB SET_ADDRESS request to the USB Device.
According to USB spec, there should have a 10ms delay before this
operation after resetting a given port.
But in original code, there is a possible path which may have no such
10ms delay:
UsbHubResetPort()->UsbHubSetPortFeature()->Stall(20)->UsbHubGetPortSt
atus()->XhcPollPortStatusChange()->(if RESET_C bit is set)->
XhcInitializeDeviceSlot()->(if RESET_C bit is set)->Stall(10)

According to the Intel SDM (325462-060US / September 2016),
> INPUT EAX = 0BH: Returns Extended Topology Information
>
> [...] Software must detect the presence of CPUID leaf 0BH by verifying
> (a) the highest leaf index supported by CPUID is >= 0BH, and
> (b) CPUID.0BH:EBX[15:0] reports a non-zero value. [...]
The "GetApicId" sections in the Ia32 and X64 "MpFuncs.nasm" files do not
perform check (b).
This causes an actual bug in the following OVMF setup:
- Intel W3550 host processor <http://ark.intel.com/products/39720/>,
- the QEMU/KVM guest's VCPU model is set to "host", that is, "the CPU
visible to the guest should be exactly the same as the host CPU".
Under "GetApicId", check (a) passes: the CPUID level of the W3550 is
exactly 11 decimal. However, leaf 11 itself is not supported, therefore
EDX is set to zero:
> If a value entered for CPUID.EAX is less than or equal to the maximum
> input value and the leaf is not supported on that processor then 0 is
> returned in all the registers.
Because we don't check (b), the "GetProcessorNumber" section of the code
is reached with an initial APIC ID of 0 in EDX on all of the APs. Given
that "GetProcessorNumber" searches the
"MP_CPU_EXCHANGE_INFO.CpuInfo[*].InitialApicId" fields for a match, all
APs enter ApWakeupFunction() with an identical "NumApsExecuting"
parameter. This results in unpredictable guest behavior (crashes, reboots,
hangs etc).
Reorganize the "GetApicId" section and add the missing check in both
assembly files.

section. Their types, default values, and token values remain unchanged.
Only UefiCpuPkg/PiSmmCpuDxeSmm consumes these PCDs, specifically on the
call stack of its entry point function, and it turns them into static or
dynamically allocated data in SMRAM:
PiCpuSmmEntry() [PiSmmCpuDxeSmm.c]
InitializeSmmTimer() [SyncTimer.c]
PcdCpuSmmApSyncTimeout
-> mTimeoutTicker
InitializeMpServiceData() [MpService.c]
InitializeMpSyncData() [MpService.c]
PcdCpuSmmSyncMode
-> mSmmMpSyncData->EffectiveSyncMode
However, there's another call path to fetching "PcdCpuSmmSyncMode", namely
SmmInitHandler() [PiSmmCpuDxeSmm.c]
InitializeMpSyncData() [MpService.c]
PcdCpuSmmSyncMode
-> mSmmMpSyncData->EffectiveSyncMode
and this path is exercised during S3 resume (as stated by the comment in
SmmInitHandler() too, "Initialize private data during S3 resume").
While we can call the PCD protocol (via PcdLib) for fetching dynamic PCDs
in the entry point function, we cannot do that at S3 resume. Therefore
pre-fetch PcdCpuSmmSyncMode into a new global variable (which lives in
SMRAM) in InitializeMpServiceData(), just before calling
InitializeMpSyncData(). This way InitializeMpSyncData() can retrieve the
stashed PCD value from SMRAM, regardless of the boot mode.

gSmmCorePrivate->CommunicationBuffer and gSmmCorePrivate->BufferSize locate at
runtime memory region. That means they could be modified by non-SMM code during
runtime.
We should cache them into SMM local variables before we verify them. After
verification, we should use the cached ones directly instead of the ones in
gSmmCorePrivate.

Change callback handler type to avoid saving PSID info in
browser temp buffer. Also clean the buffer after using it.
