874a8f961f i945: Enable changing VRAM size
On i945 the vram size is the default 8mb. It is also possible
to set it 1mb or 0mb hardcoding the GGC register in early_init.c

The intel documentation on i945, "Mobile Intel® 945 Express Chipset
Family datasheet june 2008" only documents those three options.
They are set using 3 bits. The documententation also makes mention
of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it.

The other non documented (straight forward) bit combinations allow
to change the VRAM size to those other states.

What this patch does is:
- add those undocumented registers with their respective vram size to
the i945 NB code;
- make this a cmos option on targets that have this northbridge.

TEST: build, flash to target, set cmos as desired and boot linux.
On Debian it can be found using "dmesg | grep stolen".
NOTE: dmesg message about reserved vram are quite different depending
on linux version

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.

d3060edce2 i945: make PCIe link wait sensible
Waiting for (a & 4) == 3 to become true proves futile
unless you're searching for defective hardware or
neutrino impact.

While I'm not 100% sure that this is the actual intent
(no data-sheets at hand, and the public ones are unhelpful
as usual), it's the likely correct version and it's also
boot-tested on intel/d945gclf.

While at it, replace register number with the name found
in the public datasheet.
