Routine Description:

    This routine implements the entry point into the UEFI firmware. This
    routine is called by the platform firmware, and should be called as early
    as possible. It will perform callouts to allow the platform to initialize
    further.

Arguments:

    FirmwareBaseAddress - Supplies the base address where the firmware was
        loaded into memory. Supply -1 to indicate that the image is loaded at
        its preferred base address and was not relocated.

    FirmwareLowestAddress - Supplies the lowest address where the firmware was
        loaded into memory.

    FirmwareSize - Supplies the size of the firmware image in memory, in bytes.

    FirmwareBinaryName - Supplies the name of the binary that's loaded, which
        is reported to the debugger for symbol loading.

    StackBase - Supplies the base (lowest) address of the stack.

    StackSize - Supplies the size in bytes of the stack. This should be at
        least 0x4000 bytes (16kB).

Return Value:

    This routine does not return.
