Now, I *have* seen the use of /*++ --*/ elsewhere in the tree, but this syntax is *not* described in the coding style and should not be used. While this is a delete statement, there is an addition below using the same format. The doxygen tags to use are /** and **/. Fortunately, I can't spot any of these in the rest of the set. Please send an updated version of this patch - alone if it's the only patch that needs changes, or with a v4 if such is required. > EFI_STATUS > EFIAPI > -MemoryPeim ( > - IN EFI_PHYSICAL_ADDRESS UefiMemoryBase, > - IN UINT64 UefiMemorySize > +MemoryInitPeiLibConstructor ( > + VOID > ) > { > - ARM_MEMORY_REGION_DESCRIPTOR *MemoryTable; > ARM_SMC_ARGS ArmSmcArgs; > INT32 Index; > UINTN DramSize; > @@ -82,18 +64,6 @@ MemoryPeim ( > UINTN FdTop; > BOOLEAN FoundSystemMem; > > - // Get Virtual Memory Map from the Platform Library > - ArmPlatformGetVirtualMemoryMap (&MemoryTable); > - > - // > - // Ensure MemoryTable[0].Length which is size of DRAM has been set > - // by ArmPlatformGetVirtualMemoryMap () > - // > - ASSERT (MemoryTable[0].Length != 0); > - > - // > - // Now, the permanent memory has been installed, we can call AllocatePages() > - // > ResourceAttributes = ( > EFI_RESOURCE_ATTRIBUTE_PRESENT | > EFI_RESOURCE_ATTRIBUTE_INITIALIZED | > @@ -133,8 +103,8 @@ MemoryPeim ( > > ASSERT (!DramSize); > > - FdBase = (UINTN)FixedPcdGet64 (PcdFdBaseAddress); > - FdTop = FdBase + (UINTN)FixedPcdGet32 (PcdFdSize); > + FdBase = (UINTN)PcdGet64 (PcdFdBaseAddress); > + FdTop = FdBase + (UINTN)PcdGet32 (PcdFdSize); > > // Declare memory regios to system > for (Index = MAX_DRAM_REGIONS - 1; Index >= 0; Index--) { > @@ -178,8 +148,8 @@ MemoryPeim ( > ); > }; > // Mark the memory covering the Firmware Device as boot services data > - BuildMemoryAllocationHob (FixedPcdGet64 (PcdFdBaseAddress), > - FixedPcdGet32 (PcdFdSize), > + BuildMemoryAllocationHob (PcdGet64 (PcdFdBaseAddress), > + PcdGet32 (PcdFdSize), > EfiBootServicesData); > } else { > BuildResourceDescriptorHob ( > @@ -199,16 +169,49 @@ MemoryPeim ( > Top = DramRegions[Index].BaseAddress + DramRegions[Index].Size; > > if (FdBase >= BaseAddress && FdTop <= Top) { > - Size -= (UINTN)FixedPcdGet32 (PcdFdSize); > + Size -= (UINTN)PcdGet32 (PcdFdSize); > } > > if (Size >= FixedPcdGet32 (PcdSystemMemoryUefiRegionSize)) { > FoundSystemMem = TRUE; > + PcdSet64S (PcdSystemMemoryBase, BaseAddress); > + PcdSet64S (PcdSystemMemorySize, Size); > } > } > > ASSERT (FoundSystemMem); > > + return EFI_SUCCESS; > +} > + > +/*++ Here is the incorrect addition.
