From: Chasel, Chiu Date: Tue, 19 Feb 2019 07:30:23 +0000 (+0800) Subject: UefiCpuPkg/SecCore: Wrong Debug Information for SecCore X-Git-Tag: edk2-stable201903~92 X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=08283b966ea10c0430140dc2b2951d8534d05aaa UefiCpuPkg/SecCore: Wrong Debug Information for SecCore REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1533 When SecCore and PeiCore in different FV, current implementation still assuming SecCore and PeiCore are in the same FV. To fix this issue 2 FVs will be input parameters for FindAndReportEntryPoints () and SecCore and PeiCore will be found in each FV and correct debug information will be reported. Test: Booted with internal platform successfully.
