c124e8cbc7 stm32: Deprecate SPI protocol version 2.
Now that v3 support is in the cros_ec kernel driver and depthcharge,
deprecate support for the old v2 protocol.  At some point in the future,
support for the v2 protocol will dropped entirely.

Boards that require support for the V2 protocol should enable the
following config option.

    #define CONFIG_SPI_PROTOCOL_V2

BRANCH=None
TEST=make -j buildall tests
TEST=Flash jerry, AP & EC boot successful.
TEST=`ectool protoinfo` shows only version 3 supported on jerry.
TEST=Flashrom still works on jerry.

9ccfd4553e gpio: Replace duplication in gpio declarations with X-macro file
Previously each board.h and board.c contained an enum and an array
for gpio definitons that had to be manually kept in sync, with no
compiler assistance other than that their lengths matched.

This change adds a single gpio.inc file that declares all gpio's
that a board uses and is used as an X-macro include file to
generate both the gpio_signal enum and the gpio_list array.

72481572aa Convert vboot hash calculation from task to deferred function
Vboot hash calculation takes ~350 ms during EC boot.  Since the hash
task is higher priority than the hook task, this starves all the hooks
during boot.

We could, in theory, fix that simply by swapping the priority of the
hook and hash tasks.  But then watchdog detection (in the hook task)
wouldn't detect hangs in the hash task.

A better fix (implemented here) is to convert the hashing operation to
a series of deferred function calls.  This gets rid of the hash task
entirely, and allows all pending hooks and other deferred function
calls to take place between each chunk of hashing.

On STM32-based boards, we need to bump up the hook task stack size,
since hashing is called from several layers deep in the hook task
instead of at the top of its own task, but this is still a net win of
several hundred bytes of SRAM.

BUG=chrome-os-partner:24892
BRANCH=rambi
TEST=Boot EC; look for "hash start" and "hash done" debug output.
     'taskinfo' shows at least 32 bytes of unused stack for HOOKS task.
     'hash ro' runs properly from EC console.

5ef2054c38 cleanup: Consolidate module IDs into a single shared enum

encourages standard naming of modules.

A subsequent CL will do more cleanup (standardizing on MODULE_LED

do that as a separate CL than part of this one.

c8bcc57aac cleanup: Re-enable keyboard console channel for ARM boards
Originally, the ARM boards printed the keyboard scan matrix whenever
it changed.  This generated a lot of output, so we filtered that at
the console channel level.  When we refactored the keyboard scan
module, that changed so that the scan matrix was not printed by
default, and the 'ksstate' debug command was used to enable printing
it.  But on ARM boards, 'ksstate on' wouldn't do anything without ALSO
using 'chan -1' to turn the keyboard console channel back on.  And
without the scan matrix printing by default, there's no reason to keep
the keyboard channel off by default.

b57a5fe0ed STM32L ADC driver
ADC module on STM32L is clocked by HSI oscillator, and thus we need to
switch to HSI if using MSI. After the conversion, if the system is not
in S0, clock is switched back to MSI again.

There are several register bits that can only be written when ADC is
powered down. For now, let's just power down the ADC after each
conversion.

Currently ADC watchdog is not working and is disabled on STM32L.

62e9444161 pit: Disable CONFIG_HOST_COMMAND_STATUS
With CONFIG_HOST_COMMAND_STATUS, the EC can respond to a command
with EC_RES_IN_PROGRESS, indicating to the AP that it should poll
for completion of the command with EC_CMD_GET_COMMS_STATUS.  The
kernel, however, only guarantees the atomicity of single commands.
As a result, i2c passtrough or keyboard commands could be issued
while the AP is polling for completion of a flashrom command. By
disabling CONFIG_HOST_COMMAND_STATUS, we eliminate polling of the
EC status by the AP so that there is no interleaving of commands.

f2b56fcb9f Clean up configuring GPIO alternate functions
GPIO alternate functions used to be configured throughout the code,
which made it hard to tell which ones you needed to configure yourself
in board.c.  It also sometimes (chip/lm4/i2c.c) led to GPIOs being
configured as alternate functions even if they weren't used on a given
board.

With this change, every board has a table in board.c which lists ALL
GPIOs which have alternate functions.  This is now the only place
where alternate functions are configured.  Each module then calls
gpio_init_module() to set up its GPIOs.

This also fixes a bug where gpio_set_flags() ignored most of the flags
passed to it (only direction and level were actually used).

On stm32f, gpio_set_alternate() does not exist, and pins are
configured via direct register writes from board.c.  Rather than
attempt to change that in the same CL, I've stubbed out
gpio_set_alternate() for stm32f, and will fix the register writes in a
follow-up CL.

8a66ae3182 pit: Fix watchdog help for STM32L
Clean up timer initialization code to be more general, so that we can
use timer 9 for the LSB on STM32L.  Then use timer 4 for the watchdog
helper.

BUG=chrome-os-partner:18781
BRANCH=none
TEST=From EC console:
        timerinfo -> current time still counts up properly
        waitms 2000 -> prints watchdog info before rebooting

c882edb530 Clean up SPI GPIOs
SPI is always enabled on pit, so remove #ifdefs

SPI1_CLK was aliased to AC_STATUS, which is left over from snow and
doesn't exist on pit.  That caused it to be driven high briefly during
EC boot.

Also set SPI pins for 40MHz speed so we can try faster SPI clock.

37fcfb732c Fix and enable SPI for pit
I've simplified the SPI module, since we only ever use SPI1 (and there
were already a number of places which assumed this was true).
Somewhere along the way I fixed a number of problems keeping the code
from compiling and working on STM32L.  The code isn't currently used
anywhere else, but should still work there (that is, I don't think I
broke it working on STM32F if you re-enable it on some STM32F
platform).

Also moves the handy i2cscan command to i2c_common.  The
platform-dependent interface is now i2c_xfer().

Still more to do in follow-up CLs; for example, i2c_read_string() has
platform-dependent implementation, and the i2c/i2cread console
commands aren't common yet.

01279936cb Unify lid switch processing
STM32-based platforms now use the same lid debouncing code as
LM4-based platforms, generate lid-open / lid-closed events, and
trigger lid-change hooks.

as well as future changes to mask off wake events when the lid is
closed.
