Configuring touch controllers to use edge-triggered interrupts is not
recommended as it is very easy to lose an edge when kernel drivers
disable the interrupt for one reason or another, and recovering from
this condition requires workarounds in the kernel.
Unfortunately the example setting up a touchpad used edge-triggered
interrupts, and this set up has been propagating through the boards.
Let's switch the example to use level interrupts instead.

There has been some repeated discussion about how header includes should
be formatted, specifically on the topic of chain-including. The coding
style currently doesn't say anything about the topic but clearly people
have some basic assumptions. This patch tries to codify some common
ground rules that are supposed to reflect the existing practice.

Unlike Ivy Bridge series, there isn't a method to flash coreboot
internally when running vendor firmware (yet). Until someone finds a way
to bypass flash protections, the first flash has to be done externally.

The code is based on autoport, with necessary modifications.
This laptop uses SMSC MEC1322 embedded controller, but the EC
interface is the same as the EliteBook laptops of previous generations
that use KBC1126 EC. So it still uses ec/hp/kbc1126, but does not need
EC firmware inserted into CBFS. We also need to leave the end of the
OEM flash content untouched, so the default ROM size is set to 12MiB
instead of 16MiB, and we need to modify the IFD when flashing.
Thanks to persmule for providing the laptop and pointing out how to
program the system flash chip of it.

SMMSTORE version 2 is a complete redesign of the current driver. It is
not backwards-compatible with version 1, and only one version can be
used at a time.
Key features:
* Uses a fixed communication buffer instead of writing to arbitrary
memory addresses provided by untrusted ring0 code.
* Gives the caller full control over the used data format.
* Splits the store into smaller chunks to allow fault tolerant updates.
* Doesn't provide feedback about the actual read/written bytes, just
returns error or success in registers.
* Returns an error if the requested operation would overflow the
communication buffer.
Separate the SMMSTORE into 64 KiB blocks that can individually be
read/written/erased. To be used by payloads that implement a
FaultTolerant Variable store like TianoCore.
The implementation has been tested against EDK2 master.
An example EDK2 implementation can be found here:
