> 
> A) MdeModulePkg/DxeCapsuleLib: separate BMP parsing logic

> That is very good suggestion, and we agree it is a right direction.
> I discussed with the owner of image decoder.
> We prefer adding a generic library class to convert

> not only BMP. The owner of image decoder will drive the new design.
> I filed https://bugzilla.tianocore.org/show_bug.cgi?id=175 to track that.
> I suggest we just keep the current solution as a temp solution and
> migrate to the new one once it is ready later.
> 
> B) PlatformPkg/Bds: Move test key check logic to generic part.
> This is very good suggestion and we are discussing with Tool
> team to add such detection at build time and set a PCD to indicate that.
> The generic code can use this PCD to know if there is a test key.
> I filed https://bugzilla.tianocore.org/show_bug.cgi?id=185 to track that.
> Adding such check in the generic code is very complicated, so current
> temporary solution is to let platform BDS do such check.
> The platform BDS will be cleaned up, once the tool is ready.
> 
> ==Below is V4 description==
> 1) SecurityPkg - Refine AuthenticateFmpImage() API to let caller
> input PublicKeyData and PublicKeyDataLength, instead of PCD.
> The benefit is that then this API can be used for a platform
> which stores PublicKeyData in anywhere other than PCD.
> 2) SecurityPkg - Use OFFSET_OF(WIN_CERTIFICATE_UEFI_GUID, CertData)
> for better understanding the code.
> 3) MdeModulePkg - Update CapsuleApp to let it consume
> ShellParameters protocol to get Argc and Argv.
> 4) UefiCpuPkg - Update MicrocodeCapsuleApp to let it consume
> ShellParameters protocol to get Argc and Argv.
> 5) QuarkPlatformPkg - Merge QuarkCapsule.fdf to Quark.fdf.
> 
> ==Below is V3 description==
> 1) We move all EDKII related capsule definition to SignedCapsulePkg.
> MdeModulePkg only contains FmAuthenticationLib and CapsuleApp,
> because they are generic and follow UEFI specification on FMP/ESRT
> and Microsoft platform firmware update document.
> Any capsule implementation can use them.
> 
> Here is full library classes:
> MdeModulePkg:
> 	FmpAuthenticationLib.h: new lib - follow UEFI spec. (*)
> 		Verify FMP signature of FMP Capsule
> 	CapsuleLib.h: new API ¨C ProcessCapsules()
> 		It processes all the capsules. Remove duplicated code in platform BDS.
> UefiCpuPkg:
> 	MicrocodeFlashAccessLib.h: Update Microcode region.
> SignedCapsulePkg:
> 	EdkiiSystemCapsuleLib.h ¨C Library for EDKII system FMP.
> 	IniParsingLib.h ¨C Library for INI file parsing.
> 	PlatformFlashAccessLib.h ¨C Library for write flash.
> 
> 2) We will submit 5 series.
> Series 1: Generic Update (MdeModulePkg/SecurityPkg)
> 	DxeCapsuleLib
> 	FmAuthenticationLib (*)
> 	CapsuleApp (*)
> Series 2: EDKII Capsule (SignedCapsulePkg)
> 	IniParsingLib
> 	EdkiiSystemCapsuleLib
> 	PlatformFlashAccessLib
> 	SystemFirmwareUpdate driver
> 	RecoveryModuleLoadPei driver
> Series 3: Microcode Update (UefiCpuPkg)
> 	MicrocodeFlashAccessLib
> 	MicrocodeUpdate driver.
> Series 4: Quark update
> Series 5: Vlv2 update
> 
> 3) DxeCapsuleLib: Move code that performs authentication and parsing of
> the capsule format into the implementation of the FMP Protocol.
> We move the dispatch FV code from CapsuleLib to SystemFirmwareReport.efi.
> SystemFirmwareReport.efi supports SetImage() to verify and dispatch the
> SystemFirmwareUpdate.efi, then pass thru SetImage() request to
> SystemFirmwareUpdate.efi.
> 
> Now the DxeCapsuleLib is very clean and it does not have any EDKII
> capsule format knowledge.
> 
> 4) DxeCapsuleLib: Fix issue where a reset may be too soon.
> Defer reset to 2nd pass.
> 
> 5) DxeCapsuleLib: Boot mode check is removed.
> Capsule should be populated to system table even boot mode is not BIOS_UPDATE.
> 
> 5) FmAuthenticationLib: Add zero ImageSize check.
> 
> 6) FmAuthenticationLib: Remove Authentication Library Registration.
> Each FMP Producer needs to carry its own auth algoritms(s).
> Now we have FmpAuthenticationLibPkcs7 and FmpAuthenticationLibRsa2048Sha256.
> No registration is needed.
> 
> 7) FmAuthenticationLib: Move MonotonicCount handling after Payload
> We confirmed with USWG to process MonotonicCount after PayLoad.
> 
> ==Below is V2 description==
> The V2 series patch incorporated the feedback for V1.
> 
> There are 3 major updates.
> 1) BDS is update to display a warning message if TEST key
> is used to sign recovery image or capsule image.
> So a production BIOS should always use its own production singing
> key for the capsule image generation. A production BIOS should
> never use test key.
> 2) IniParsingLib is enhanced to do more sanity check for invalid
> input. The detail data format is added in IniParsingLib.h header
> file. If there is any vialation, the OpenInitFile() API will
> return failure.
> 3) The *Bios* keyword is renamed to *SystemFirmware* in any
> header file or c file data structure definition.
> 
> The rest is minor update, such as add help info, clean
> up debug message, coding style.
> 
> ==Below is V1 description==
> This series patch provides sample on how to do signed capsule update
> and recovery in EDKII.
> 
> This series patch is also checked into git@github.com:jyao1/edk2.git.
> 
> The feature includes:
> 1) Define EDKII signed system BIOS capsule format.
> 2) Provide EDKII signed system BIOS update sample.
> 3) Provide EDKII signed recovery sample.
> 4) Provide Microcode update sample for X86 system.
> 5) Update Quark to use new capsule/recovery solution.
> 6) Update Vlv2(MinnowMax) to use new capsule/recovery solution.
> 
> The signed capsule/recovery solution is in MdeModulePkg.
> The capsule in IntelFrameworkModulePkg is deprecated.
> The Microcode update solution is in UefiCpuPkg.
