Hi Heinrich,

Currently running the SCT fails on x86. The EFI shell overrides U-Boot's Simple Text Output Protocol. When ConsoleLoggerPrintWithPageBreak() is invoked with ConsoleInfo == NULL a crash occurs.
Debugging requires running the debug version of the UEFI shell. We can use `add-symbol-file` in gdb to point to Build/Shell/DEBUG_GCC/X64/ShellPkg/Application/Shell/Shell/DEBUG/Shell.dll and the load address of Shell.efi.
The debug version of the UEFI shell checks several requirements and fails to run without them:
- HOB list (only on x86)
- HII configuration protocol
- DXE services table
Implement the missing requirements.
When starting image add the image load address to the debug output.

Please can you document how to actually run UEFI like this? Also, is it possible to add a test for this new code?
