-Module Name:
-
- SecMain.c
-
-Abstract:
- Unix emulator of SEC phase. It's really a Posix application, but this is
- Ok since all the other modules for NT32 are NOT Posix applications.
-
- This program processes host 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
- host file and mapping it directly to memory addresses.
-
- The system.cmd script is used to set host environment variables that drive
- the configuration opitons of the SEC.

-/**
- Transfers control to a function starting with a new stack.
-
- Transfers control to the function specified by EntryPoint using the new stack
- specified by NewStack and passing in the parameters specified by Context1 and
- Context2. Context1 and Context2 are optional and may be NULL. The function
- EntryPoint must never return.
-
- If EntryPoint is NULL, then ASSERT().
- If NewStack is NULL, then ASSERT().
-
- @param EntryPoint A pointer to function to call with the new stack.
- @param Context1 A pointer to the context to pass into the EntryPoint
- function.
- @param Context2 A pointer to the context to pass into the EntryPoint
- function.
- @param NewStack A pointer to the new stack to use for the EntryPoint
- function.
- @param NewBsp A pointer to the new BSP for the EntryPoint on IPF. It's
- Reserved on other architectures.
