Module Name:
SecMain.c
Abstract:
WinNt emulator of SEC phase. It's really a Win32 application, but this is
Ok since all the other modules for NT32 are NOT Win32 applications.
This program processes Windows environment variables and figures out
what the memory layout will be, how may FD's will be loaded and also
what the boot mode is.
The SEC registers a set of services with the SEC core. gPrivateDispatchTable
is a list of PPI's produced by the SEC that are availble for usage in PEI.
This code produces 128 K of temporary memory for the PEI stack by opening a
Windows file and mapping it directly to memory addresses.
The system.cmd script is used to set windows environment variables that drive
the configuration opitons of the SEC.

Routine Description:
This service is called from Index == 0 until it returns EFI_UNSUPPORTED.
It allows discontiguous memory regions to be supported by the emulator.
It uses gSystemMemory[] and gSystemMemoryCount that were created by
parsing the Windows environment variable EFI_MEMORY_SIZE.
The size comes from the varaible and the address comes from the call to
WinNtOpenFile.
Arguments:

MemorySize - Return size in bytes of the memory region
Returns:

Module Name:
UnixThunk.c
Abstract:
Since the SEC is the only program in our emulation we
must use a Tiano mechanism to export APIs to other modules.
This is the role of the EFI_UNIX_THUNK_PROTOCOL.
The mUnixThunkTable exists so that a change to EFI_UNIX_THUNK_PROTOCOL
will cause an error in initializing the array if all the member functions
are not added. It looks like adding a element to end and not initializing
it may cause the table to be initaliized with the members at the end being
set to zero. This is bad as jumping to zero will crash.
gUnix is a a public exported global that contains the initialized
data.
