Ard Biesheuvel 16dc5b68fc MdeModulePkg/EbcDxe: use EfiBootServicesCode memory for thunks
The EBC driver emits thunks for native to EBC calls, which are short
instructions sequences that bridge the gap between the native execution
environment and the EBC virtual machine.

Since these thunks are allocated using MemoryAllocationLib::AllocatePool(),
they are emitted into EfiBootServicesData regions, which does not reflect
the nature of these thunks accurately, and interferes with strict memory
protection policies that map data regions non-executable.

So instead, create a new helper EbcAllocatePoolForThunk() that invokes the
AllocatePool() boot service directly to allocate EfiBootServicesCode pool
memory explicitly, and wire up this helper for the various architecture
specific thunk generation routines.

Pete Batard 3e2c784302 MdeModulePkg/EbcDxe: reorganize EBC header definitions
VM related defs are now in EbcVmTest.h, and opocode related definitions in
Ebc.h.
Because it is used by both the EBC Debugger and driver,
EbcDebugSignalException() sees its definition factorized in
EbcDebuggerHook.h.

jyao1 fa97cbf4ef 1) Fix GCC version EBC interpreter bug.
Add missing EFIPAI for EbcInterpret and ExecuteEbcImageEntryPoint().
	Get return value in EbcLLCALLEXNative(), remove EbcLLGetReturnValue().

2) Fix IA32 EBC interpreter bug on MOVsnw and MOVsnd.

3) Some cleanup
	Add missing ReturnEBCStack() for IA32 build.
	Remove unnecessary EbcLLGetStackPointer() for X64 and IPF build.
	Remove deadcode EbcLLGetStackPointer() and EbcLLGetReturnValue() in IA32/X64/IPF ASM code.
	Dump more info in CommonEbcExceptionHandler().

lgao4 c8ad2d7a29 Clean up the private GUID definition in module Level.
0. Remove the unused private GUID from module source files.
1. Use gEfiCallerIdGuid replace of the private module GUID.
2. Add the public header files to define HII FormSet and PackageList GUID used in every HII driver.
3. Move two EBC protocols for debug purpose from EBC driver to MdeModulePkg Include directory.

qhuang8 f3f2e05db8 Clean up to update the reference of the these macros:
EFI_SIGNATURE_16 -> SIGNATURE_16
  EFI_SIGNATURE_32 -> SIGNATURE_32
  EFI_SIGNATURE_64 -> SIGNATURE_64
  EFI_FIELD_OFFSET -> OFFSET_OF
  EFI_MAX_BIT      -> MAX_BIT
  EFI_MAX_ADDRESS  -> MAX_ADDRESS
These macros are not defined in UEFI spec. It makes more sense to use the equivalent macros in Base.h to avoid alias.
