[coreboot] Asrock IMB-A180 not booting

[Bruce Griffith]

Dave pointed out that the device ID is actually listed in your coreboot
spew, which shows:

	>> PCI: 00:01.0 [1002/9834] enabled

I was wrong last night on the mainboard IDs.  The "H" indicates the
mainboard variant.  The "E" in IMB-A180E indicates the processor type.
Yours is the low-power CPU and is the same as mine.  So the only
difference between our boards is that mine has an LVDS connector.  I guess
yours must have two HDMI connectors.

There seems to be something wrong with your SeaBIOS build.  You might want
to look at the SeaBIOS config options in
./payloads/external/SeaBIOS/Makefile.inc.  Increase the SeaBIOS debug
level by adding a line under the config recipe (echo
"CONFIG_DEBUG_LEVEL=3" >> $(OUT)/seabios/.config).

I don't know how you are building, but you might try a completely clean
build of coreboot using the following commands:

	mv .config my.config
	make distclean
	cp my.config .config
	make oldconfig
	make

After build, CBFS should look something like this:

	coreboot.rom: 4096 kB, bootblocksize 816, romsize 4194304, offset
0x0
	alignment: 64 bytes

You should see something like the following when SeaBIOS is invoked:
