a9c5ea08d0 Revert "CMOS: Add set_option and rework get_option."
This reverts commit eb7bb49eb5b48c39baf7a256b7c74e23e3da5660.

Stepan pointed out that "s" means string, which makes the following statement
in this commit message invalid: "Since we either have reserved space (which
we shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go."

9ceae905f1 CMOS: Add set_option and rework get_option.
To ease some of my debugging pain on the unichrome, i decided i needed to
move FB size selection into cmos, so i could test a size and then reset it
to the default after loading this value so that the next reboot uses the
(working) default again. This meant implementing set_option in parallel to
get_option.

get_option was then found to have inversed argument ordering (like outb) and
passing char * and then depending on the cmos layout length, which made me
feel quite uncomfortable. Since we either have reserved space (which we
shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go. So all users of
get_option now have their arguments inversed and switched from using ints
to unsigned ints now.

The way get_cmos_value was implemented forced us to not overlap byte and to
have multibyte values be byte aligned. This logic is now adapted to do a
full uint32_t read (when needed) at any offset and any length up to 32, and
the shifting all happens inside an uint32_t as well. set_cmos_value was
implemented similarly. Both routines have been extensively tested in a
quick separate little program as it is not easy to get this stuff right.

build_opt_tbl.c was altered to function correctly within these new
parameters. The enum value retrieval has been changed strol(..., NULL, 10)
to stroul(..., NULL, 0), so that we not only are able to use unsigned ints
now but so that we also interprete hex values correctly. The 32bit limit
gets imposed on all entries not marked reserved, an unused "user_data" field
that appeared in a lot of cmos.layouts has been changed to reserved as well.

a29ec0633a Restructure the PCI IDs list for the ICH* chipsets from ICH/ICH0 up to
ICH5/ICH5R (more to follow) in preparation of further 82801xx improvements.

Use human-readable names for the PCI ID #defines.
Rename *_ISA to *_LPC as per datasheet.
The 82801DBM only has 3 (not 4) USB devices, looks like a copy-paste error.

The fixes in southbridge code are only to keep the build working for now,
any real improvements will only go into the 82801xx code in future.

This is abuild-tested so it shouldn't break anything.

f1cf1f7c3a Ever wondered where those "setting incorrect section attributes for
rodata.pci_driver" warnings are coming from? We were packing those
structures into a read-only segment, but forgot to mark them const.

Despite its size, this is a fairly trivial patch created by a simple
search/replace

ef79223156 Bug fixes: read all 16 bits of DMA configuration; set up NMI/SERR handling in I/O space not PCI space. Comment out posted-memory-write code that looks to have been mis-inherited.

4f9265fdc6 - kill typo so resources are not mixed up in amdk8/northbridge.c
- Enable resources on the lpc bus.  PCI now longer do this by
  default for their children unless they are bridges.

7003ba4a88 - First stab at running linuxbios without the old static device tree.
Things are close but not quite there yet.
