the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

Some mainboards need to disable the power button to avoid turning off
right after being turned on, while other boards ship with a jumper over
the power button and should allow the user to configure the behavior.
This adds infrastructure in the form of four mutually exclusive options
which can be selected in a mainboard Kconfig (power button forced on/off,
and user-controllable with default on/off) and one result bool which
source code can test. (Enable the button or not.)
The options have been implemented in CS5536 code and for all mainboards
which select SOUTHBRIDGE_AMD_CS5536, but should be used also by other
chipsets where applicable. Note that if chipset code uses the result
bool ENABLE_POWER_BUTTON, then every board using that chipset must
select one out of the four control options in order to build.
All touched boards should have unchanged behavior, except
pcengines/alix1c, traverse/geos and lippert/hurricane-lx where the
power button can now be configured by the user.
Build tested for alix1c, alix2d, hurricane-lx and wyse-s50. Confirmed
to work as advertised on alix1c both with button enabled and disabled.
Includes additional traverse/geos changes from Nathan and
lippert/hurricane-lx changes from Jens to correctly use the new
feature on those boards.

the Rumba does not have the mmx related lines (which _are_ in

Major changes:
1. Separate resource allocation into:
A. Read Resources
B. Avoid fixed resources (constrain limits)
C. Allocate resources
D. Set resources
Usage notes:
Resources which have IORESOURCE_FIXED set in the flags constrain the placement
of other resources. All fixed resources will end up outside (above or below)
the allocated resources.
Domains usually start with base = 0 and limit = 2^address_bits - 1.
I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is
still there for resources. Some platforms may want to change that, but I didn't
want to break anyone's board.
Resources are allocated in a single block for memory and another for I/O.
Currently the resource allocator doesn't support holes.

Add comment from Rudolf,
"
VC is virtual channel. Its used for isochronous transfer of data to sound card.
The virtual channel guarantee "on time" delivery. In other words it sets up a
channel for data to sound card, which means that that arrivs in time and there will
be no interuptions in audio stream.

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."

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.

You can see this by executing commands like this:
grep -r pci_assign_irqs coreboot/src/*
This basically AMD/LX based boards: pcengines/alix1c,
digitallogic/msm800sev, artecgroup/dbe61, amd/norwich, amd/db800.
Also for AMD/GX1 based boards need a patch
[http://www.pengutronix.de/software/ptxdist/temporary-src/references/geode-5530.patch]
for the right IRQ setup.
AMD/GX1 based boards is: advantech/pcm-5820, asi/mb_5blmp, axus/tc320,
bcom/winnet100, eaglelion/5bcm, iei/nova4899r, iei/juki-511p.
I have two ideas.
1. Delete duplicate code from AMD/LX based boards.
2. Add IRQ routing for AMD/GX1 boards in coreboot.
The pirq.patch for IRQ routing logically consist from of two parts:
First part of pirq.patch independent from type chipsets and assign IRQ for
ever PCI device. It part based on AMD/LX write_pirq_routing_table() function.
Second part of pirq.patch depends of type chipset and set PIRQx lines
in interrupt router. This part supports only CS5530/5536 interrupt routers.
IRQ routing functionality is included through PIRQ_ROUTE in Config.lb.

code and had several other problems, e.g. it enabled write access to the

The new code
- has 'ide0_enable' and 'ide1_enable' config options (which actually
work) to enable/disable the primary/secondary IDE interface in
Config.lb.
- Does _not_ enable write access to the ROM (or is there some good
reason to do that? If so, it should at least have a config option).
- Contains a bit more documentation.
- Uses readable (and documented) #defines instead of hardcoded magic values.
