A global flag oprom_is_loaded was used to indicate to
U-boot that VGA option ROM was loaded and run, or that
native VGA init was completed on GMA device.
Implement this feature without dependency to CHROMEOS option
and replace use of global variable oprom_is_loaded with call
to gfx_get_init_done().

With the recent improvement 3d6ffe76f8,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly
if necessary.

small gap of only 728 bytes between mrc.bin and mrc.cache, with the
64 KiB alignment maintained for mrc.cache -- assuming systemagent-r6
is used. The gap was just under 64 KiB before.
With this change, it is easier to accommodate fallback and normal
boot stages without having to manually place the stages in the highly

The SystemAgent contains a mini-hd audio controller at PCI 0:3.0
which uses the same verb table init sequence as the southbridge.
In order to avoid two copies of the verb table loading code I
separated out the HDA verb table functions into a file that can
be re-used and then added a minihd driver to the haswell northbridge.
The minihd verb table is the same across devices so it can live
within the minihd driver rather than needing to be specified in
each separate mainboard.
I also fixed up the driver for lynxpoint HDA by following the

Without HDMI cable plugged in driver does not find any codec,
and it does not seem to re-probe when HDMI is connected. We may
be missing kernel patches for this.
