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
