a4677e426a cpu/x86/smm/smihandler: Apply cosmetic changes
Use define for SSA base address.
Move EM64T area to 0x7c00 and add reserved area of size 0x100,
as there's no indication that the address 0x7d00 exists on any
platform.

No functional change.

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.

Note: I have no idea what eptp is. It's just listed in the
haswell BWG. The offsets should not be changed.

51cb26d92a SMM: Fix state save map for sandybridge and TSEG
There are enough differences that it is worth defining the
proper map for the sandybridge/ivybridge CPUs.  The state
save map was not being addressed properly for TSEG and
needs to use the right offset instead of pointing in ASEG.

To do this properly add a required southbridge export to
return the TSEG base and use that where appropriate.

3aa067f595 Add support to run SMM handler in TSEG instead of ASEG
Traditionally coreboot's SMM handler runs in ASEG (0xa0000),
"behind" the graphics memory. This approach has two issues:
- It limits the possible size of the SMM handler (and the
  number of CPUs supported in a system)
- It's not considered a supported path anymore in newer CPUs.

Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and
local #defines into globally configurable kconfig options (and Options.lb
options for as long as newconfig still exists) which can be enabled

The respective menu items only appear if a board is selected where the
chipset code actually provides such additional DEBUG output.

All three variables default to 0 / off for now.

Also, drop a small chunk of dead/useless code in the
src/northbridge/via/cn700/raminit.c file, which would otherwise break
