I'm not sure how, but it appears locally that patch 27 had an "ENQ" character introduced at the beginning of the patch file. This resulted in: 1. Actual patch 26 (correct): https://edk2.groups.io/g/devel/message/74179 2. This version of patch 27 (incorrect): https://edk2.groups.io/g/devel/message/74180 which retains the subject line from actual patch 26 ("CoffeelakeSiliconPkg...") but the contents from actual patch 27 (KabylakeSiliconPkg files modified). Patch 27 should have had the subject "KabylakeSiliconPkg: Remove SmmSpiFlashCommonLib" (as indicated in the cover letter). I am still collecting feedback on v1. I will check for this in the v2 patch files. - Michael On 4/19/2021 2:07 AM, Chiu, Chasel wrote: > > Hi Michael, > > Please rename subject to "KabylakeSiliconPkg". > With above change, Reviewed-by: Chasel Chiu > > Thanks, > Chasel > > >> -----Original Message----- >> From: mikuback@linux.microsoft.com >> Sent: Friday, April 16, 2021 10:32 AM >> To: devel@edk2.groups.io >> Cc: Chiu, Chasel ; Chaganty, Rangasai V >> >> Subject: [edk2-platforms][PATCH v1 26/35] CoffeelakeSiliconPkg: Remove >> SmmSpiFlashCommonLib >> >> REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3307 >> >> The library has been consolidated with instances in other Intel silicon packages >> as a single instance in IntelSiliconPkg >> >> Cc: Chasel Chiu >> Cc: Sai Chaganty >> Signed-off-by: Michael Kubacki >> --- >> >> Silicon/Intel/KabylakeSiliconPkg/Pch/Library/SmmSpiFlashCommonLib/SpiFlashC >> ommon.c | 196 -------------------- >> >> Silicon/Intel/KabylakeSiliconPkg/Pch/Library/SmmSpiFlashCommonLib/SpiFlashC >> ommonSmmLib.c | 54 ------ >> Silicon/Intel/KabylakeSiliconPkg/Pch/Include/Library/SpiFlashCommonLib.h >> | 98 ---------- >> >> Silicon/Intel/KabylakeSiliconPkg/Pch/Library/SmmSpiFlashCommonLib/SmmSpiFl >> ashCommonLib.inf | 53 ------ >> 4 files changed, 401 deletions(-) >> >> diff --git >> a/Silicon/Intel/KabylakeSiliconPkg/Pch/Library/SmmSpiFlashCommonLib/SpiFlas >> hCommon.c >> b/Silicon/Intel/KabylakeSiliconPkg/Pch/Library/SmmSpiFlashCommonLib/SpiFlas >> hCommon.c >> deleted file mode 100644 >> index 7ee7ffab5001..000000000000 >> --- >> a/Silicon/Intel/KabylakeSiliconPkg/Pch/Library/SmmSpiFlashCommonLib/SpiFlas >> hCommon.c >> +++ /dev/null >> @@ -1,196 +0,0 @@ >> -/** @file >> - Wrap EFI_SPI_PROTOCOL to provide some library level interfaces >> - for module use. >> - >> -Copyright (c) 2017, Intel Corporation.
