DxeIpl module cannot find DXE entry point

[Hristo Mihaylov <hristo.mihaylov@prodrive-technologies.com>]

Hello,

This is my first time posting to a mailing list. I am building a custom platform that fails when handing off control from PEIM to DXE.

Here's the error:

```
ASSERT_EFI_ERROR (Status = Not Found)
ASSERT c:\users\hrimih\documents\work\scalable\bios\MdeModulePkg\Core\DxeIplPeim\DxeLoad.c(480): !EFI_ERROR (Status)
```

In the platform only the DXE phase is compressed, using LZMA. I suspect that it's not being decompressed and the module cannot find the DXE entry point.

This is the relevant .FDF part.

```
[FV.FVMAIN]
BlockSize          = 0x10000
FvAlignment        = 16
ERASE_POLARITY     = 1
MEMORY_MAPPED      = TRUE
STICKY_WRITE       = TRUE
LOCK_CAP           = TRUE
LOCK_STATUS        = TRUE
WRITE_DISABLED_CAP = TRUE
WRITE_ENABLED_CAP  = TRUE
WRITE_STATUS       = TRUE
WRITE_LOCK_CAP     = TRUE
WRITE_LOCK_STATUS  = TRUE
READ_DISABLED_CAP  = TRUE
READ_ENABLED_CAP   = TRUE
READ_STATUS        = TRUE
READ_LOCK_CAP      = TRUE
READ_LOCK_STATUS   = TRUE
FvNameGuid         = CDBB7B35-6833-4ed6-9AB2-57D2ACDDF6F0

[FV.FVMAIN_COMPACT]
FvAlignment        = 16
ERASE_POLARITY     = 1
MEMORY_MAPPED      = TRUE
STICKY_WRITE       = TRUE
LOCK_CAP           = TRUE
LOCK_STATUS        = TRUE
WRITE_DISABLED_CAP = TRUE
WRITE_ENABLED_CAP  = TRUE
WRITE_STATUS       = TRUE
WRITE_LOCK_CAP     = TRUE
WRITE_LOCK_STATUS  = TRUE
READ_DISABLED_CAP  = TRUE
READ_ENABLED_CAP   = TRUE
READ_STATUS        = TRUE
READ_LOCK_CAP      = TRUE
READ_LOCK_STATUS   = TRUE
FvNameGuid         = 27A72E80-3118-4c0c-8673-AA5B4EFA9613

FILE FV_IMAGE = 9E21FD93-9C72-4c15-8C4B-E77F1DB2D792 {
  SECTION GUIDED EE4E5898-3914-4259-9D6E-DC7BD79403CF PROCESSING_REQUIRED = TRUE {
    SECTION FV_IMAGE = FVMAIN
  }
}
```

Then in the .DSC I have:

```
  MdeModulePkg/Core/DxeIplPeim/DxeIpl.inf {
    <LibraryClasses>
      NULL|MdeModulePkg/Library/LzmaCustomDecompressLib/LzmaCustomDecompressLib.inf
 }
```

And for the DXE Main:

```
  MdeModulePkg/Core/Dxe/DxeMain.inf {
    <LibraryClasses>
      DevicePathLib|MdePkg/Library/UefiDevicePathLib/UefiDevicePathLib.inf
      NULL|MdeModulePkg/Library/DxeCrc32GuidedSectionExtractLib/DxeCrc32GuidedSectionExtractLib.inf
      NULL| MdeModulePkg/Library/LzmaCustomDecompressLib/LzmaCustomDecompressLib.inf
    <PcdsFixedAtBuild>
      gEfiMdePkgTokenSpaceGuid.PcdMaximumLinkedListLength|0
  }
```

I expect that this PEIM module will decompress the DXE partition and find the entry point:

```
DxeCoreEntryPoint|MdePkg/Library/DxeCoreEntryPoint/DxeCoreEntryPoint.inf
```

Any advice on how I can debug/fix this?
