2. Added assert() for AsmFxRestore() in x86LowLevel.c of BaseLib 3. Added assert() for LongJump() in LongJump.c of BaseLib 4. Changed parameter type of Value from "IN" to "IN OUT" for InterLockedComparedExchanged32/64/pointer() functions to sync with MWG-0.55a 5. Changed functions header of all BitField functions of BaseLib, BaseIoLibIntrinsic, BasePciCf8Lib, BasePciExpressLib, BasePciLibCf8, BasePciLibPciExpressLib DxeIoLibCpuIo, PeiIoLibCpuIo etc, to follow MWG-0.55a. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@565 6f19259b-4bc3-4df7-8a09-765794883524
