1. In AsmFuncs.asm, DebugSupport, Vect2Desc() function will use hardcode CS to fill the IDT. 20h for Ia32.If the system CS is changed by CPU driver, this driver can not work. System maybe crash.
2. In EBC, RegisterExceptionCallback() can not restore the environment and I add some enhancements.
3. In Image.c, CoreLoadImageCommon never return EFI_SECURITY_VIOLATION when SecurityStatus == EFI_SECURITY_VIOLATION.
4. In Variable.c, 1. There're additional unnecessary loop. All blocks will be gone through even if all the data has been written. We should check the "CurrWriteSize" to see if there's no more data to write, and stop the for loop immediately. 2 "if.else." can be merged to save lines of code.
5. in FvbServices,c, Checksum calculation error.

1. In dependency.c, DXE Dispatcher doesn't check the dependency expression boundary correctly.
2. In page.c, a misspelling code in DXE core memory service code, duplicate code.
3. In gcd.c, according to DXE CIS 0-91 spec, When GcdAllocateType is EfiGcdAllocateMaxAddressSearchBottomUp or EfiGcdAllocateMaxAddressSearchTopDown, then the GCD memory space map is searched from the lowest address up to BaseAddress (or from BaseAddress down to the lowest address) looking for unallocated memory ranges of Length bytes. Here, BaseAddress itself is inclusive, that is, any range in [0, BaseAddress] is allowable. But current code BaseAddress to be exclusive.
4. In Ebcinit.c, EbcDebugRegisterPeriodicCallback() not check whether it is already registered.
5. In Ebcinit.c, EbcDebugRegisterExceptionCallback() not check whether it is already registered.
6. In Ebcinit.c, EbcDebugSignalException() does not assign value to EbcContext.ControlFlags.
7. In Ebcinit.c, EBC: StatusCodeValue should use EFI_SOFTWARE_EBC_EXCEPTION.
8. In Ebcinit.c, EbcDebugRegisterExceptionCallback() does not check ExceptionType
9. In ElTorito.c, BlockIo and DiskIo failed in SCT when there is CD in CD-ROM.
10. In Mbr.c, MBR code can't handle some situations. That is when there are 3 partitions in HD, if delete the first partition, it will not be able to recognize the other two partitions, and if delete the second partition, it will not be able to recognize the third partition.

Added PeCoffLoaderGetMachineType to the PeCoffGetEntryPointLibrary Class. Document to be updated.
Added the PeCoffLoaderImageReadFromMemory() and PeCoffLoaderRelocateImageForRuntime () to the PcCoffLib.
Updated EfiImage.h and removed EFI_IMAGE_OPTIONAL_HEADER and EFI_IMAGE_NT_HEADERS as they were replaced with checking the MachineType.
PeCoffLib – Added checks for MachineType so the PeCoff lib can load any PE32 or PE32+ image. The relocations are still limited to IA32, X64, IPF, and EBC. I also added a re-relocator function to remove PeLoader Code from Runtime Lib. Even though there is only one instance of the re-relocator I wanted to get all the PeCoff loader code together.
Replaced DEBUG_CODE() macro with DEBUG_CODE_START() and DEBUG_CODE_END() so you can debug through the DEBUG_CODE() macros. Also removed PE/COFF code and replaced with library usage.
I also updated the IO Instrinsic lib to use _ReadWriteBarrior() to help with sync problems
