{which_ras[0],which_ras[1],which_ras[2],which_ras[3]} <= 4'b0100; // /RAS1

mem_selected <= 1'b1;


Disable autoconfig
you can probably leave autoconfig on and just remove the call for that 1 x 2mb fastmem area, and be left with 6mb fastmem in 2 chunks, but i will leave the proof to the pros.

The source for the a600 is the same as the a500
