Abstract:

    This file contains the global structure stored inside flash.
	This structure is used by dec21140.lib, boot loader and kernel.

//	Okay, here is the pain:
//	EDBG_ADDR is defined in halether.h which can only be included in Kernel build.
//	Our eglobal.h uses this type and we are not including halether.h in bootloader.
//	So, Please define EDBG_ADDR before including eglobal.h
