This patch switches every last part of Coreboot on ARM over to Thumb
mode: libpayload, the internal libgcc, and assorted assembly files. In
combination with the respective depthcharge patch, this will switch to
Thumb mode right after the entry point of the bootblock and not switch
back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).

In order to support probing I2C devices when the controller is
in ACPI mode the mainboard needs to decalre them in the proper
scope with the address/interrupt information. The touchpad devices
are ATML0000/ELAN0000 and the touchscreen is ATML0001 so they can
be distinguished in userland scripts based on ID. There is also
a special "ISTP" node that indicates whether the devices is a
touchpad (=1) or touchscreen (=0) in case this is useful to drivers.
These names may not be final but they are a starting point and can
be easily changed.
Atmel devices also have a bootloader mode which needs to be
declared as a separate device. Unfortunately it does not work as
expected to have multiple I2cSerialBus() resources declared in a
single device and have it select properly, even with the use of
StartDependentFn(), so bootloader devices are declared separately.
The original devices are left in \_SB scope and are only enabled
if the I2C controllers are in PCI mode. The new devices are only
enabled if the I2C controllers are in ACPI mode.

This improves boot time in 2 ways for a firmware upgrade:
1. Normally MRC would detect the S0 state without an MRC cache
even though it's told to the S5 path. When it observes this
state a cold reset occurs. The cold reset stays in S5 for
at least 4 seconds which is time observed by the end user.
2. As the EC was running RW code before the reset after firmware
upgrade it will still be running the older RW code. Vboot will
then reboot the EC and the whole system to put the EC into RO
mode so it can handle the RW update.
The issues are mitigated by detecting the system is in S0 with
no MRC cache and the EC isn't in RO mode. Therefore we can do the
reboot without waiting the 4 secs and the EC is running RO so
the 2nd reboot is not necessary.

This is a first cut at the u-boot cli. It builds and loads and runs
and has no commands. That's next.
Interestingly, this is code right from our u-boot tree, and it's full
of style violations which I don't intend to fix.
Remove dependency on anything else, but this won't work until the
libpayload serial drivers for arm are set up.
BUG=None
TEST=build and boot on nyan and get a u-boot cli prompt.

KBD_IRQ# is moved to GPIO SC101, with SC50 going back to its original
SERIRQ function.
Note that this change breaks Rambi 1.5 keyboard functionality.

There needs to be an ACPI linkage to provide the power resource
needed to wake this device so the kernel will enable the SCI
before going to suspend.
A link is added for both NIC and WLAN, but it is only tested
on the NIC.
This is a forward port from Duncan's beltino patch.

- Remove some unused functions from CPU participant that were
confusing the userland component since the CPU does not have
an ACPI managed sensor.
- Guard the charger participant with an ifdef so it can be
left out if not supported.
- Use the EC methods for setting auxiliary trip points and for
handling the event when those trip points are crossed.
- Add _NTT _DTI _SCP methods for thermal sensors. I'm not
clear if these are required or not but they seem to be expected
by the other DPTF framework components.

The EC now supports two auxiliary programmable trip points for
thermal monitoring. These are expected to be used by DPTF and
need to be exported.
In order to support these the header was updated from the latest
chrome ec source.
