[coreboot] v2[PATCH]RCA RM4100 i82830 support

I hate to say it Corey, but this just sends it into an infinite loop.  
Does it make a difference that the onboard memory is located in slot2  
and slot1 is empty? Here is what I have:

Thanks - Joe

static void do_ram_command(const struct mem_controller *ctrl, uint32_t  
command, uint32_t addr_offset)
{
	int i;
	uint8_t reg8;
	uint32_t reg32;

	/* Configure the RAM command. */
	reg32 = pci_read_config32(ctrl->d0, DRC);
	/* Clear bits 29, 10-8, 6-4. */
	reg32 &= 0xdffff88f;
	reg32 |= command << 4;
       /* If RAM_COMMAND_NORMAL set the refresh mode and IC bit. */
	if (command == RAM_COMMAND_NORMAL) {
	reg32 |= ((RAM_COMMAND_REFRESH << 8) | (RAM_COMMAND_IC << 29));
       }
	pci_write_config32(ctrl->d0, DRC, reg32);

	/* RAM_COMMAND_NORMAL affects only the memory controller and
	   doesn't need to be "sent" to the DIMMs. */
