This removes the code from PrePi and MemoryInitPeiLib that keeps the primary
FV around forever so that DXE phase code can reuse some of the code inside
the PrePi module.

The BeagleBoard platform uses PeCoffLib and CustomDecompressLib
implementations that invoke the library code that resides in the PrePi
module via pointers exposed via special GUIDed HOBs. This is a nice hack,
but not necessarily something we want to carry in reference code.
So as a first step, move the libraries that expose this reused code into
BeagleBoardPkg, and remove it from EmbeddedPkg.

Clone the PrePi implementation for BeagleBoardPkg, so we can start
removing some of the awkward optimizations that we'd rather not keep
in reference code. Note that we only clone the unicore ARM flavor,
which is all we need for BeagleBoard.
In the case of PrePi, it involves libraries included by the SEC
startup code that are exposed to DXE core via HOBs containing function
pointers, which forces us to keep the primary FV reserved in memory.

The common MemoryInitPeiLib implementation preserves the primary FV
holding the PrePi module and the compressed secondary FV, and removes
the memory it occupies from the memory map, hiding it from the OS.
The only platform that actual requires this is BeagleBoardPkg, since
it exposes the PeCoff and LZMA libraries in PrePi to DXE core via
special HOBs. So let's give BeagleBoard its own MemoryInitPeiLib, so
that we can clean up the generic version.

Avoid the need to preserve all memory exposed by PrePi indefinitely
by removing the 'feature' that exposes the PE/COFF and LZMA libraries
via special HOBs to other modules that may want to reuse the code.

Now that PrePi no longer exposes its internal code via special HOBs,
we can remove the special handling of the primary FV, which needed to
be reserved so that DXE core could call into the PE/COFF and LZMA
libraries in the PrePi module.

Hmm ...
Do we need this local declaration?
Is there some header we could use?
If not - could we move it out to PrePi.h?

Thanks. Pushed as c6e51751e026..73fcbb48665e
I have taken the liberty of reordering this patch with the one that
clones PrePi for Beagle, so this fix is applied to the clone as well.

Hi Ard, Meenakshi,
I am having a problem I cannot explain the reason for, with this commit on
an ARM64 platform.
ArmPlatformPkg/MemoryInitPeiLib: don't reserve primary FV in memory
Now that PrePi no longer exposes its internal code via special HOBs,
we can remove the special handling of the primary FV, which needed to
be reserved so that DXE core could call into the PE/COFF and LZMA
libraries in the PrePi module.

And there is no way to do source-level debug because FV image cannot be

As soon as I revert this commit

Could you please explain me what I am doing wrong?

Thanks for response Ard,
No, this does not help.
In ArmPlatformGetVirtualMemoryMap () the platform reads a Pcd describing
SDRAM memory configuration (regions),
For each described region it creates a memory resource HOB like this:
if (PrepareMemoryResourceHob (
MyDDRInfo[Index].Address,
MyDDRInfo[Index].Size,
MyDDRInfo[Index].Size + 1,
Reserve ? EFI_RESOURCE_MEMORY_RESERVED : EFI_RESOURCE_SYSTEM_MEMORY
)) {
UINTN SizeGB;
TotalHighMemAdded += MyDDRInfo[Index].Size;
SizeGB = MyDDRInfo[Index].Size >> 30;
DEBUG((
EFI_D_INFO,
"HighMemMap: Added DDR %a area (%d). Start address: 0x%llx, size
%llu %a (0x%llx)\n",
Reserve ? "reserved" : "highmem",
Index + 1,
MyDDRInfo[Index].Address,
SizeGB ? SizeGB : MyDDRInfo[Index].Size >> 20,
SizeGB ? "GiB" : "MiB",
MyDDRInfo[Index].Size
));
Index++;
}
} else {
MyDDRInfo[Index].Address = 0;
MyDDRInfo[Index].Size = 0;
}
Thus it reports described and filled in areas of memory like this:
HighMemMap: Added DDR highmem area (1). Start address: 0x8F101000, size 1
GiB (0x70EFF000)
HighMemMap: Added DDR highmem area (2). Start address: 0x880000000, size 14
GiB (0x380000000)
HighMemMap: Added DDR highmem area (3). Start address: 0x9000000000, size 16
GiB (0x400000000)
HighMemMap: Added DDR highmem area (4). Start address: 0xA000000000, size 16
GiB (0x400000000)
HighMemMap: Added DDR reserved area (1). Start address: 0x8F000000, size 1
MiB (0x101000)
IS this not the right way to describe memory HOBs?
With your proposed change assertion happens very early, here:
ASSERT_EFI_ERROR (Status = Not Found)
ASSERT [ArmPlatformPrePiMPCore] /uefi/ArmPlatformPkg/PrePi/PrePi.c(157):
!EFI_ERROR (Status)
So it cannot DecompressFirstFv().
If I don't apply your suggested change and revert the commit I mentioned
earlier, it works fine...
Thank you,
Vladimir

To clarify, PreparememoryResourceHob looks like this:
BOOLEAN
PrepareMemoryResourceHob (
IN EFI_PHYSICAL_ADDRESS Address,
IN UINT64 MemSize,
IN UINT64 MaxAllowedSize,
UINTN MemType
)
{
BOOLEAN HobCreated;
HobCreated = FALSE;
if ((MemSize > 0) && (MemSize <= MaxAllowedSize)) {
// Additional memory is available. Declare it.
EFI_RESOURCE_ATTRIBUTE_TYPE ResourceAttributes;
ResourceAttributes = SYSTEM_MEMORY_ATTRS;
if (MemType != EFI_RESOURCE_SYSTEM_MEMORY) {
ResourceAttributes = RESERVED_MEMORY_ATTRS;
}
BuildResourceDescriptorHob (
MemType,
ResourceAttributes,
Address,
MemSize);
HobCreated = TRUE;
}
return HobCreated;
}
And SYSTEM_MEMORY_ATTRS:
#define RESERVED_MEMORY_ATTRS \
EFI_RESOURCE_ATTRIBUTE_PRESENT | \
EFI_RESOURCE_ATTRIBUTE_WRITE_PROTECTED | \
EFI_RESOURCE_ATTRIBUTE_WRITE_PROTECTABLE | \
EFI_RESOURCE_ATTRIBUTE_INITIALIZED | \
EFI_RESOURCE_ATTRIBUTE_READ_PROTECTED | \
EFI_RESOURCE_ATTRIBUTE_READ_PROTECTABLE | \
EFI_RESOURCE_ATTRIBUTE_UNCACHEABLE | \

Hi Vladimir
How re-allocation or say drivers are dispatched on your system.
Could you check addresses, where FV is kept and where this is getting dispatched
Thx
