QuarkSocPkg: Add new package for Quark SoC X1000
Changes for V4 ============== 1) Remove Unicode character from C source file 2) Move delete of QuarkSocPkg\QuarkNorthCluster\Binary\QuarkMicrocode from QuarkPlatformPkg commit to QuarkSocPkg commit Changes for V2 ============== 1) Sync with new APIs in SmmCpuFeaturesLib class 2) Use new generic PCI serial driver PciSioSerialDxe in MdeModulePkg 3) Remove PCI serial driver from QuarkSocPkg 4) Apply optimizations to MtrrLib from MtrrLib in UefiCpuPkg 5) Convert all UNI files to utf-8 6) Replace tabs with spaces and remove trailing spaces 7) Add License.txt Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Michael Kinney <michael.d.kinney@intel.com> Acked-by: Jordan Justen <jordan.l.justen@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@19286 6f19259b-4bc3-4df7-8a09-765794883524

This routine accepts a request to "open" a region of SMRAM. The
