+ This FSP API provides multi-phase memory and silicon initialization, which brings greater modularity to the existing

+ This allows the bootloader to add board specific initialization steps throughout the MemoryInit and SiliconInit flows as needed.
+ The FspMemoryInit() API is always called before FspMultiPhaseMemInit(); it is the first phase of memory initialization. Similarly,
+ the FspSiliconInit() API is always called before FspMultiPhaseSiInit(); it is the first phase of silicon initialization.
+ After the first phase, subsequent phases are invoked by calling the FspMultiPhaseMem/SiInit() API.
+ The FspMultiPhaseMemInit() API may only be called after the FspMemoryInit() API and before the FspSiliconInit() API;
+ or in the case that FSP-T is being used, before the TempRamExit() API. The FspMultiPhaseSiInit() API may only be called after

Hi Chasel,
I have a few comments for you.
First, we should have a platform provided LibraryClass for running code in between multi-phase actions. Right now you just have this comment in IntelFsp2WrapperPkg/Library/FspWrapperMultiPhaseProcessLib/PeiFspWrapperMultiPhaseProcessLib.c:
//
// Platform handling can be added here to take care specific actions for each phase
// before returning control back to FSP.
//
I would like a new LibraryClass added: FspWrapperPlatformMultiPhaseLib
This would implement a single function:
VOID
EFIAPI
FspWrapperPlatformMultiPhaseHandler (
IN UINT8 ComponentIndex,
IN UINT32 PhaseIndex
);
Add an implementation of this in IntelFsp2WrapperPkg/Library/BaseFspWrapperPlatformMultiPhaseLibSample. That .inf will provide an implementation of FspWrapperPlatformMultiPhaseHandler() that doesn't do anything (just leave it empty).
Then, invoke FspWrapperPlatformMultiPhaseHandler() at the point where you have that comment above in FspWrapperMultiPhaseHandler().
The *BoardPkg can provide an SOC specific implementation. Typically the real *BoardPkg implementation will look something like this:
VOID
EFIAPI
FspWrapperPlatformMultiPhaseHandler (
IN UINT8 ComponentIndex,
IN UINT32 PhaseIndex
)
{
switch (ComponentIndex) {
case FspMultiPhaseMemInitApiIndex:
switch (PhaseIndex) {
case 1:
PeiServicesInstallPpi (mSomePlatformSpecificNotifyPpi1);
break;
}
break;
case FspMultiPhaseSiInitApiIndex:
switch (PhaseIndex) {
case 1:
PeiServicesInstallPpi (mSomePlatformSpecificNotifyPpi2);
break;
}
break;
}
}
The exact specifics would vary by SOC design and are out of scope for this patch series. But you do need to provide the base case of "do nothing" in IntelFsp2WrapperPkg.
Second, in IntelFsp2WrapperPkg/Library/FspWrapperMultiPhaseProcessLib/PeiFspWrapperMultiPhaseProcessLib.c:
case EnumFspVariableRequestSetVariable:
if (WriteVariableSupport) {
Status = VariablePpi->SetVariable (
VariablePpi,
FspVariableRequestParams->VariableName,
FspVariableRequestParams->VariableGuid,
*FspVariableRequestParams->Attributes,
(UINTN)*FspVariableRequestParams->DataSize,
FspVariableRequestParams->Data
);
} else {
return EFI_UNSUPPORTED;
}
Instead of return EFI_UNSUPPORTED; it should be Status = EFI_UNSUPPORTED;. Same thing with EnumFspVariableRequestQueryVariableInfo.
Third, in FspWrapperVariableRequestHandler(), after you call EnumMultiPhaseCompleteVariableRequest you need to check if one of the FSP_STATUS_RESET_REQUIRED_* status codes is returned and if so invoke CallFspWrapperResetSystem().
Fourth, there is a bug in IntelFsp2WrapperPkg/FspsWrapperPeim/FspsWrapperPeim.c:
FspWrapperVariableRequestHandler (&FspHobListPtr, FspMultiPhaseMemInitApiIndex);
Should be this:
FspWrapperVariableRequestHandler (&FspHobListPtr, FspMultiPhaseSiInitApiIndex);
Fifth, I noticed some spelling errors in IntelFsp2WrapperPkg/Library/FspWrapperMultiPhaseProcessLib/PeiFspWrapperMultiPhaseProcessLib.c:
// Firstly querry variable request informaiton from FSP.
Should be:
// Get the variable request information from FSP.
And this:
// Firstly querry FSP for how many phases supported.
Should be:
// Query FSP for the number of phases supported.
Thanks,
Nate

//
// Platform handling can be added here to take care specific actions for each phase
// before returning control back to FSP.

I would like a new LibraryClass added: FspWrapperPlatformMultiPhaseLib
This would implement a single function:
VOID
EFIAPI
FspWrapperPlatformMultiPhaseHandler (
IN UINT8 ComponentIndex,
IN UINT32 PhaseIndex
);
Add an implementation of this in IntelFsp2WrapperPkg/Library/BaseFspWrapperPlatformMultiPhaseLibSample. That .inf will provide an implementation of FspWrapperPlatformMultiPhaseHandler() that doesn't do anything (just leave it empty).
Then, invoke FspWrapperPlatformMultiPhaseHandler() at the point where you have that comment above in FspWrapperMultiPhaseHandler().
The *BoardPkg can provide an SOC specific implementation. Typically the real *BoardPkg implementation will look something like this:
VOID
EFIAPI
FspWrapperPlatformMultiPhaseHandler (
IN UINT8 ComponentIndex,
IN UINT32 PhaseIndex
)
{
switch (ComponentIndex) {
case FspMultiPhaseMemInitApiIndex:
switch (PhaseIndex) {
case 1:
PeiServicesInstallPpi (mSomePlatformSpecificNotifyPpi1);
break;
}
break;
case FspMultiPhaseSiInitApiIndex:
switch (PhaseIndex) {
case 1:
PeiServicesInstallPpi (mSomePlatformSpecificNotifyPpi2);
break;
}
break;
}
}
The exact specifics would vary by SOC design and are out of scope for this patch series. But you do need to provide the base case of "do nothing" in IntelFsp2WrapperPkg.
Second, in IntelFsp2WrapperPkg/Library/FspWrapperMultiPhaseProcessLib/PeiFspWrapperMultiPhaseProcessLib.c:
case EnumFspVariableRequestSetVariable:
if (WriteVariableSupport) {
Status = VariablePpi->SetVariable (
VariablePpi,
FspVariableRequestParams->VariableName,
FspVariableRequestParams->VariableGuid,
*FspVariableRequestParams->Attributes,
(UINTN)*FspVariableRequestParams->DataSize,
FspVariableRequestParams->Data
);
} else {
return EFI_UNSUPPORTED;
}
Instead of return EFI_UNSUPPORTED; it should be Status = EFI_UNSUPPORTED;. Same thing with EnumFspVariableRequestQueryVariableInfo.
Third, in FspWrapperVariableRequestHandler(), after you call EnumMultiPhaseCompleteVariableRequest you need to check if one of the FSP_STATUS_RESET_REQUIRED_* status codes is returned and if so invoke CallFspWrapperResetSystem().
Fourth, there is a bug in IntelFsp2WrapperPkg/FspsWrapperPeim/FspsWrapperPeim.c:
FspWrapperVariableRequestHandler (&FspHobListPtr, FspMultiPhaseMemInitApiIndex);
Should be this:
FspWrapperVariableRequestHandler (&FspHobListPtr, FspMultiPhaseSiInitApiIndex);
Fifth, I noticed some spelling errors in IntelFsp2WrapperPkg/Library/FspWrapperMultiPhaseProcessLib/PeiFspWrapperMultiPhaseProcessLib.c:
// Firstly querry variable request informaiton from FSP.
Should be:
// Get the variable request information from FSP.
And this:
// Firstly querry FSP for how many phases supported.
Should be:
// Query FSP for the number of phases supported.
Thanks,
Nate
