How would I provide a fake spd array? Here is the situation. My board
has the onboard memory without a SPD, I could just hardcode this into
the northbridge raminit.c. But I don't want to do that so people that
may want to use the northbridge src for other boards won't have to
deal with it. So right now I have auto.c call a function that runs in
between sdram_set_spd_registers and sdram_enable, like this:
sdram_set_spd_registers(memctrl);
onboard_sdram_set_registers(memctrl);
sdram_enable(0, memctrl);
This function, onboard_sdram_set_registers manually sets up the regsters.
Anyways I would also like to get the smbus_write_byte write going to
setup my tv-out registers on my tv-out chip?
Thanks - Joe
