Please review the attached patch that adds Quark SoC compatibility to the CpuExceptionHandlerLib in the UefiCpuPkg.
Some EDK II libraries assume capabilities that are not available on Quark SoC. With these changes, applications and drivers built for IA32 are compatible with Quark SoC. These patches do not modify X64 specific sources or SSE/SSE2 specific sources. Change Summary: =============== 1) Remove use of CMOVx from IA32 assembly. This matches compiler flags for all supported C compilers. 2) Use CPUID Leaf 01 to detect CPU capabilities for CLFLUSH, Cache Line Size, FXSAVE/FXTSTOR, CR4.DE, and CR4.OSFXR 3) Use CPUID Family/Model/Stepping to detect support for MSR_IA32_APIC_BASE_ADDRESS. Quark SoC does not support this MSR. 4) Add stride PCD to MdeModulePkg to support 16550 UARTs with a register stride that is not 1 byte. Quark SoC uses a stride of 4 bytes.
