f3f36faf35 src (minus soc and mainboard): Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

31312b21d1 sb/intel/i82801gx: Use common Intel SMM code
Use the common Intel code to set up smm and the smihandler. This is
expected to break S3 resume and other smihandler related
functionality as this code is meant to be used with
CONFIG_SMM_TSEG. Platforms (i945, pineview, x4x) using this
southbridge will adapt the CONFIG_SMM_TSEG codepath in subsequent
patches.

Tested on Intel D945GCLF, still boots fine but breaks S3 resume
support because it hangs on SMI.

a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

811787abd5 i82801gx: read RTC status register to prevent IRQ storm
My Thinkpad appeared dead. After investigation, it turned out
that the RTC Alarm was triggering an RTC PM1 SMI, but the SMI
handler didn't read the status register, so it was triggered again.

This is a really nasty situation, as it means you have to dissemble
your Notebook just to unplug the RTC battery.

bfe8e5186e SMM: don't overwrite SMM memory on resume
Overwriting the SMM Area on resume leaves us with
all variables cleared out, i.e., the GNVS pointer
is no longer available, which makes SMIF function
calls impossible.

f4dc1a73e4 SMM: add defines for APM_CNT register
in the current code, the defines for the APM_CNT (0xb2) register
are duplicated in almost every place where it is used. define those
values in cpu/x86/smm.h, and only include this file.

And while at it, fixup whitespace.

c21b054acc SMM: add mainboard_apm_cnt() callback
motherboards can use this hook to get notified if someone writes
to the APM_CNT port (0xb2). If the hook returns 1, the chipset
specific hook is also skipped.

836ae29ee3 first round name simplification. drop the <component>_ prefix.
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

This should help to reduce the code duplication for Rudolf's K8/VIA SMM
