• BaseMemoryLib:
Modify some Aassert()s conditions to sync with MWG 0.56d Modify some defects in function header. • PostCodeLib: Implement PeiDxePostCodeLibReportStatusCode. • Misc Rename BaseDebugLibReportStatusCode to PeiDxeDebugLibReportStatusCode Remove tabs in all .c and .h files in MdePkg. Rename PeiServicesReinstallPpi() to PeiServicesReInstallPpi() Adjust some minor coding style in PeCoffLoaderGetEntryPointerLib() git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@626 6f19259b-4bc3-4df7-8a09-765794883524
