[Need help][how to config dm8168 2G ddr]

Hi all:

     i have a question need your help.

     when i use dm8168 to do my designning ,i use 2G ddr in my board.

     i use 128M space for linux,  sr1 space is 336.5M and sr2 space is 233.75M. According to <DM81xx_DVR_RDK_Memory_Map.pdf>, the last 1G ddr space is left and used for linux kernel.

     my quesiton is as following:

     Now my s1 and s2 space is limited according to my design, so i wonder could i make use of the last 1G ddr to exlarge the space of s1 and s2?

     if it is possible, how could i config the space distribution of ddr, or could you offer me a config_2g.bld file?

    thank you so much.
