FYI: Merge in progress...

The ARIMA HDAMA now boots, and everything looks like it is working properly.

Converting everything else still remains but we now have a working example
to look at.

We are down to one device tree instead of two.
And hardwaremain has been reduced to:

void hardwaremain(int boot_complete)
{
	/* the order here is a bit tricky. We don't want to do much of 
	 * anything that uses config registers until after PciAllocateResources
	 * since that function also figures out what kind of config strategy
	 * to use (type 1 or type 2). 
	 * so we turn on cache, then worry about PCI setup, then do other 
	 * things, so that the other work can use the PciRead* and PciWrite*
	 * functions. 
	 */
	struct lb_memory *lb_mem;

	post_code(0x80);

	/* displayinit MUST PRECEDE ALL PRINTK! */
	console_init();
	
	post_code(0x39);
	printk_notice("LinuxBIOS-%s%s %s %s...\n", 
		linuxbios_version, linuxbios_extra_version, linuxbios_build,
		(boot_complete)?"rebooting":"booting");

	post_code(0x40);

	/* If we have already booted attempt a hard reboot */
	if (boot_complete) {
		hard_reset();
	}

	/* FIXME: Is there a better way to handle this? */
	init_timer(); 

	/* pick how to scan the bus. This is first so we can get at memory size. */
	printk_info("Finding PCI configuration type.\n");
	pci_set_method();
	post_code(0x5f);
	dev_enumerate();
	post_code(0x66);
	/* Now do the real bus.
	 * We round the total ram up a lot for thing like the SISFB, which 
	 * shares high memory with the CPU. 
	 */
	dev_configure();
	post_code(0x88);

	dev_enable();

	dev_initialize();
	post_code(0x89);

	/* Now that we have collected all of our information
	 * write our configuration tables.
	 */
	lb_mem = write_tables();

#if CONFIG_FS_STREAM == 1
	filo(lb_mem);
#else
	elfboot(lb_mem);
#endif
}

There is more scrubbing on the horizon but so for things look good.
