TMS570LC4357: EMIF SDRAM Configuration

/** @example example_emif_sdram.c
*   This example code configures EMIF module to write and execute from SDRAM
*
*   @b Step @b 1:
*
*   Create a new project.
*
*   Navigate: -> File -> New -> Project
*
*   @image html example_createProject.jpg "Figure: Create a new Project"
*
*   @b Step @b 2:
*
*   Configure driver code generation: 
*
*   Navigate: -> TMS570LCxx /RM5x -> Enable Drivers
*   - Enable EMIF driver
*   - Enbale GIO driver
*   - Disable others
*
*   @b Step @b 3:
*   
*   Configure pinmux:
*      - Enable all EMIF pins except EMIF_RNW
*      - Enable all EMIF outputs including EMIF_CLK
*
*   Navigate PINMUX->Pin Muxing
*
*   Enable checkbox EMIF and disable EMIF_RNW at ball D17
*
*   @image html emif_pinmux1.jpg "Figure: Pinmux configuration"
*
*   Navigate PINMUX->Special Pin Muxing
*
*   @image html emif_pinmux2.jpg "Figure: Special Pinmux configuration"
*
*   @b Step @b 4:
*
*   Configure EMIF
*
*   Navigate: -> EMIF -> EMIF General
*     - Enable EMIF SDRAM
*     - Disable others
*
*   Navigate: -> EMIF -> EMIF SDRAM
*     - Fill in the timing parameters
*
*   @image html EMIF_config.jpg "Figure: Configuration for ISSI IS42S16400F"
*
*   @b Step @b 5:
*
*   Generate code
*
*   Navigate: -> File -> Generate Code
*
*   @image html generateCode.jpg "Figure: Generate Code"
*   
*   @b Step @b 6:
*
*   Modify the linker command file
*      - Add the follwing under MEMORY
*            - SDRAM  (RWX) : origin=0x80000000 length=0200000000
*      - Add the follwing under SECTIONS
*            - 	.blinky_section :  RUN = SDRAM, LOAD = FLASH0 | FLASH1
					   LOAD_START(BlinkyLoadStart), LOAD_END(BlinkyLoadEnd),  LOAD_SIZE(BlinkySize),
					   RUN_START(BlinkyStartAddr ), RUN_END(BlinkyEndAddr )
*
*   @image html EMIF_linker.jpg "Figure: Linker command file"
*
*   @b Step @b 7:
*
*   Copy the source code below into your sys_main.c (or) replace sys_main.c with this file.
*
*   The example file example_mibspi_loopback.c can also be found in the examples folder: ../HALCoGen/examples
*
*   @note HALCoGen generates an empty main function in sys_main.c.
