The ich7 datasheet "Intel® I/O Controller Hub 7 (ICH7)
Family" has a reg called GEN_PMCON_1 in which
c3 can automatically be upgraded to c4.
This is already set in coreboot.

The sound card on the x60 is not configured in coreboot.
This causes the headphones not to be automatically
detected/used when inserted which it does on the vendor
bios. The internal microphone is also not set as default.
I found on the coreboot wiki how to get the config from vendor bios.
In GNU/linux run:
for x in /sys/class/sound/card0/hw*; do cat "$x/init_pin_configs" > pin_"$(basename "$x")"; done
for x in /proc/asound/card0/codec#*; do cat "$x" > "$(basename "$x")"; done
which gives the pin config of the vendor bios.

This patch sets msr bits to enable dynamic L2 cache
which is a requirement for C4E, which is also enabled
by this patch.
the bit for C2E is also set.
Those msr bits are taken from later cpus and seem to work fine.
C2 state performs particularly bad. Before this patch it consumed ~17-18W.
After this patch it dropped to 14W.
Idle power usage (C4) seems to remain very similar.

352M vram seems to be quite unstable on targets with
4GB or more. 256M has yet to show issues on different
ram configurations. This might be a good default for libreboot.

This patch enables all vram sizes and sets the default to 352M for
libreboot.
Normally users have to clear their vram for this to happen. using
"nvram -c random"
But there a 2 better option:
coreboot provides to always load the defaults in its menuconfig
update the flashscript to reset cmos

this is identical to the patch enabling c4 state on x60

This should fix the RTC century byte issue (fix merged upstream).
Some patches were removed, in those cases where they became merged upstream.
