ebf92ecc83 Kunimitsu: Add S0ix on SLP_S0 assertion
On assertion of SLP_S0, EC goes to S0ix while system is in Lucid sleep
and EC is eligable to enter heavy sleep idle task.
Wakeup from S0ix by lid open, any key press, power button or track pad
will be done by PCH block by asserting SLP_S0.
At S0ix, 1 msec pulse will be generated every 8sec and this signal
should be ignored since this is NOT S0ix entry/exit related and defered
interrupt for SLP_S0 were added.

BRANCH=master
BUG=none
TEST=in OS shell, run following commands.
	Following command is valid with coreboot with S0ix patches.
	"echo freeze > /sys/power/state"
	then,
	Measure EC power consumption and compare it with one in S0.
	And on EC console, there should be NO periodic message, "power
	state 4 = S0ix, in 0x001d" every 8 sec.

a8f2e3625e add the 'extension' command framework
This patch introduces a facility which would allow to compile in
callbacks for arbitrary commands passed over various communication
protocols.

Typically this will be used for testing, when various test commands
are multiplexed over an existing protocol.

The callbacks are associated with 16 bit command codes. On input the
callback receives a buffer, containing the command's argument, the
size of the command argument and the maximum size of the buffer. On
output the callback stores processing result in the same buffer and
updates the size to the actual amount of returned data.

Callback descriptors are stored in a dedicated read only section which
is scanned by extension_route_command() to find a callback associated
with a certain command code.

A console channel is also being introduced to allow controlling
console output generated by extension commands handlers.

66a72f0b6e motion: minium interval between motion task now a variable
On Ryu EVT2, where sensors share a 100kb i2c bus with other device,
when the sensors set to their maximal frequency and sampling interval
set to 5ms, the power management task would wait forever for the i2c
lock.
Increase the minimal amount of time the task can wait from 3ms to 8ms in
that case.
This is not an issue for Ryu PVT where the sensors are on a separate SPI
bus. However, on EVT, when setting the accelerometer/gyro over 125Hz, EC
won't be able to deliver the data in non-batched mode.

397dbec3d6 console: Add support for using EC-3PO console.
This commit introduces a new CONFIG_* option.  To utilise the
experimental console, simply define the following config option in the
board's board.h file.

     #define CONFIG_EXPERIMENTAL_CONSOLE

This is a temporary option which allows the EC console to be work with
the EC-3PO interactive console interface.  When this option is enabled,
the EC expects commands to packed in a particular format.  This is for
command integrity and allows the interpreter to perform automatic
command retrying in the event that a character is dropped from the sent
command.

It also removes a lot of the console editing methods since they are now
being served by EC-3PO.

Once the EC-3PO interpreter is pulled into servod, we can enable this
feature by default and the config option can go away.

62691cac03 cr50: make customized RO work
This patch completes introduction of building of proper RO and RW
images for cr50.

A few small mods were required:

- both RO and RW images have to be signed, using the same dedicated
  signer, but with different keys, dev_key.pem is not needed any more.

- the RW image offset is not at the half of available flash, a chip
  specific value of 16K is used instead.

   The suggested new image layout is as follows:

094a81f5de cleanup: Handle signed RW images a bit cleaner
For signed EC RW images (CONFIG_RWSIG), there's no point in
embedding the public key or signature into the image itself since

takes that out and just points to where the pubkey and signature

1b34f4bae7 Cr50: Add support for flash write & erase
This adds flash support for the SoC.

BUG=chrome-os-partner:44745
BRANCH=none
TEST=manual

Pick an unused section of flash and use the flasherase and
flashwrite commands to test it. The flashwrite command fills a
buffer with bytes, counting up (0x00, 0x01, 0x02, 0x03, ...),
then writes that buffer to the address given.

Note that the "md" command uses the absolute address, while the
flash commands use the offset address within the flash memory.

For example:

Test bank 0:

This sensor also has integrated support for Directional

Gesture recognition can be done in software (by the EC) or in
hardware, by the sensor itself.
Add variable to compile gesture.c only in the software case.

8900884cad als: Disable task when host is not running
If the ALS is not enabled in S3/S5 states then it will generate
errors when trying to read so should be gated.

This could be done with a check for chipset_state or adding a
new CONFIG_ALS_POWER_GPIO to check.  However the ALS is also not
needed when the host is in S3/S5 yet the task continues to run
in the background every 1 second.

This commit adds a new task enable/disable hook to disable the
task when the system is suspended and enable the task when it
is resumed.

In order to fit this new task in glados the als console command
is guarded by a new config option.  Since this is not a very
frequently used/needed console command it is disabled by default.

And finally the kunimitsu and strago boards try to enable ALS
but they never actually enabled the ALS task so this new code was
failing to build because TASK_ID_ALS did not exist.  Also samus
was enabling it but as TASK_NOTEST so tests will fail, though
they are disabled globally on samus.

BUG=chrome-os-partner:43493
BRANCH=none
TEST=enable ALS on glados and successfully build and use it,
also successfully build EC and tests for kunimitsu, strago,
and samus which are the other boards that use the ALS task.
