TMS320C6748: TMS320C6748 replace DDR by EMIFA SDRAM

Part Number: TMS320C6748

hi,
    now, our board replace DDR by EMIFA SDRAM(0x4000 0000 0x5FFF FFFF 512M).
    so we have some problems:
        1.write image to flash by uart: normally,we use sfh_OMAPL138.exe .but then find that
    this way separate in two parts:trasmit image to DDR,copy image from DDR to flash.how about EMIFA SDRAM?
        2.if system can bootup by  copy flash image to EMIFA SDRAM? normally,compiler use XXX.cmd ,can see:
            MEMORY
        {
          DRAM        org=0xC0000000 len=0x04000000 /* SDRAM */
          L2RAM       org=0x11800000 len=0x00040000 /* DSP L2RAM */  
          SHARED_RAM  org=0x80000000 len=0x00020000 /* DDR for program */
          AEMIF       org=0x60000000 len=0x02000000 /* AEMIF CS2 region */
          AEMIF_CS3   org=0x62000000 len=0x02000000 /* AEMIF CS3 region */
        }
        can we add EMIFA SDRAM by this?:
        {
            AEMIF_CS0    org=0x40000000 len=0x04000000 /* EMIFA SDRAM */
        }

please reply as soon as prossble,  thank you very mush!
