UefiLib:
Add two new interfaces of EfiCreateEventLegacyBootEx & EfiCreateEventReadyToBootEx Fix a bug in EfiCreateEventLegacyBoot & EfiCreateEventReadyToBoot. (#51) PciLib: Add missing ASSERT()s in PciReadBuffer() & PciWriteBuffer() (#70) IoLib Add ASSERT()s to check alignment. MemoryAllocationLib: For AllocateXXXCopyBuffer(). Add ASSERT()s for cases when allocations fails. BaseLib: Change the return type of InternalMathModU64x32 from UINT64 to UINT32 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@416 6f19259b-4bc3-4df7-8a09-765794883524
