DRAM sizing

Dear Ecos:

Just started work on the ATCA-7010(dual IXP2800 ARM platform).
Intel has delivered the base board with the DRAM size hardcoded in Redboot to
768MG. CYGMEM_REGION.ram_SIZE is the default value and hal_dram_size
is set to 768MG(hal_platform_setup.h/hal_plaform_extras.h). I need to modify the code to dynamically determine the amount of RDRAM and
then pass this value to the linux kernel(via ATAG_MEM?).
Somewhat new to this so would appreciate some quidance.


                                                               Thanks,
                                                                     Jerry
