EVM6678 Read And Write to DDR3 from linux

Hi

with 6678EVM How can read and write to DDR3 from linux on core0 (hlos side)?

in this EVM DDR3 has the start address of 0x8000000, Can use this syntax:

int* ddr3Ptr;
ddr3Ptr = 0x8000000;
*ddr3Ptr = 1;

and if i use this syntax:

memcpy(dstPtr, ddr3Ptr, 100);

Dose linux use EDMA to this transfer?

thank alot.
