Changes for V4 ============== 1) Move delete of QuarkSocPkg\QuarkNorthCluster\Binary\QuarkMicrocode from QuarkPlatformPkg commit to QuarkSocPkg commit 2) Fix incorrect license header in PlatformSecLibModStrs.uni Changes for V3 ============== 1) Set PcdResetOnMemoryTypeInformationChange FALSE in QuarkMin.dsc This is required because QuarkMin.dsc uses the emulated variable driver that does not preserve any non-volatile UEFI variables across reset. If the condition is met where the memory type information variable needs to be updated, then the system will reset every time the UEFI Shell is run. By setting this PCD to FALSE, then reset action is disabled. 2) Move one binary file to QuarkSocBinPkg 3) Change RMU.bin FILE statements to INF statement in DSC FD region to be compatible with PACKAGES_PATH search for QuarkSocBinPkg Changes for V2 ============== 1) Use new generic PCI serial driver PciSioSerialDxe in MdeModulePkg 2) Configure PcdPciSerialParameters for PCI serial driver for Quark 3) Use new MtrrLib API to reduce time to set MTRRs for all DRAM 4) Convert all UNI files to utf-8 5) Replace tabs with spaces and remove trailing spaces 6) 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@19287 6f19259b-4bc3-4df7-8a09-765794883524
