9797f654d9 Makefile: Add support for per-board symlinks to top level
Previously if you were working on a single board you had to add BOARD=
to all of your make command lines.  Now if you are in a board directory
you can just use "make", or "make clean", or any other top level make
command.

This commit also adds support for a top level "make flash" command that
can be used from the board directories as well.  This command uses
openocd and requires that the board provides an openocd-flash.cfg file.

7746b32e17 GPIO: Move definition of alternate functions to gpio.inc
This is a straightforward conversion of existing tables
into X-Macro style definitions for the GPIO alternate
functions.  This change in itself, is not particularly
powerful, but having all GPIO settings in a single file
makes a board easier to understand.

3500c28b50 gpio: Reformat gpio.inc files to use longer than 80-column lines
These files are tabular data more than source code.  We discussed
and concluded that the 80-column limit makes them harder to read,
not easier.  This commit reformats them to take advantage of
longer lines, mainly by putting per GPIO comments on the end of
the line that defines the GPIO.

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.

8a9817a5c7 cleanup: Combined i2c unwedge code into one common function
Refactored the i2c unwedge code to place it in the common directory
so that any EC chip can use it.

Added to the STM32F and LM4 boards, code to automatically detect and
unwedge the i2c bus at the start of an i2c transaction. Note that STM32L
already had this ability.

To enable unwedging of the i2c port though, the gpio pins for SDA and
SCL must be defined in the i2c_ports[] array in the board.c file. This
allows the i2c module to bit bang the unwedging for the given port. If
SDA and SCL are not defined for the port, then the unwedge code will
not run.

BUG=chrome-os-partner:26315, chrome-os-partner:23802
BRANCH=none
TEST=Manual testing on machines with different EC chips.

Testing made extensive use of https://chromium-review.googlesource.com/66389
in order to force wedging of the i2c bus so that we can attempt to unwedge
it. Note that you can easily test if the bus is wedged by running i2cscan.

On pit and spring:
On pit, after each of the following, I verified that the bus was automatically
unwedged.
On spring, the unwedge only runs at reboot, so, for the non-reboot wedge
commands, I manually ran console command unwedge, and verified that the bus
became unwedged.
(1) Bit bang a transaction but only read part of the response.
    Command to wedge: i2cwedge 0x90 0 2 2
(2) Bit bang a transaction to do a "write" and stop while the other side is
    acking. Command to wedge: i2cwedge 0x90 0 1
(3) Same as (1) but do a reboot instead of returning and see
    that the unwedge works at init time w/ no cancelled transactions.
    Command to wedge: i2cwedge 0x90 0 6 2
(4) Same as (2) but do a reboot instead of returning and see
    that the unwedge works at init time w/ no cancelled transactions.
    Command to wedge: i2cwedge 0x90 0 5

On glimmer:
Added code to call i2c_unwedge in accel_init(). Then tested unwedging the
accelerometer with the following. One extra difficulty testing this with
the accelerometer is that sometimes the bit you stop on is high, which
means it won't be wedged at all, the next start transaction will reset
the bus. So, sometimes running i2cwedge won't wedge the bus and sometimes
it will depending on the acceleration data.
(1) Big bang transaction to do a "read" of accelerometer and stop partway:
    i2cwedge 0x1c 0x0f 2 2
    i2cscan to make sure bus is actually wedged
    i2cunwedge
    i2cscan to make sure bus is now unwedged.
(2) Bit bang transaction to do a "read" and stop partway, then reboot:
    i2cwedge 0x1c 0x0f 6 2.
    i2cscan to verify that the bus is working after the reboot.

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.

TEST=Boot EC; look for "hash start" and "hash done" debug output.

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.

However, if we use this:

  struct foo_t foo[] = {

    [FOO_B] = {...},
  };

and we accidentally get one wrong:

  struct foo_t foo[] = {

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.

39dc0c0329 snow: Remove remnants of partial SPI support
We started SPI development on the Snow platform, but then repurposed
some of the GPIOs to use for I2C arbitration.  Now that we have Pit,
we'll never go back and finish SPI on Snow, so this code can be removed.

Remove the remaining dead code from Snow.  This makes it easier to do the
GPIO alternate function refactoring.

af77729737 Add build-time checks on board-specific array sizes.
We've been declaring a bunch of statically-sized arrays:

  extern struct foo_t foo[FOO_COUNT];

And then initializing them like so:

  struct foo_t foo[FOO_COUNT] = {
    /* blah */
  };

That only catches cases where we initialize with too many entries. It
doesn't catch cases where we haven't initialized enough. This change tests
for both cases like so:

  extern struct foo_t foo[];

  struct foo_t foo[] = {
    /* blah */
  };
  BUILD_ASSERT(ARRAY_SIZE(foo) == FOO_COUNT);

The affected arrays are:

  adc_channels[ADC_CH_COUNT]
  gpio_list[GPIO_COUNT]
  temp_sensors[TEMP_SENSOR_COUNT]
  x86_signal_list[X86_SIGNAL_COUNT]
  i2c_ports[I2C_PORTS_USED]

d3dffe2532 stm32: Add CHIP_FAMILY defines
Previously, code which needed to work on all STM32F platforms needed
to specify them by name (CHIP_VARIANT_stm32f100 ||
CHIP_VARIANT_stm32f10x), and we needed extra symlinks in the
chip/stm32/ directory to allow the build system to find
family-specific files.

Add a CHIP_FAMILY level of abstraction, so that things which are
common across all STM32F platforms don't need to specify every STM32F
variant.  Make the chip build look for family-specific filenames
instead of variant-specific filenames (except for config*.h, which is
actually variant specific).

In the few places where things actually are variant-specific, keep
using the existing CHIP_VARIANT defines.

Code refactoring only; no functional changes.

1695760e95 Rename GPIO_HI_Z macros to more descriptive GPIO_ODR_HIGH/LOW
GPIO_HI_Z was a bit misleading (it's high impedance by default, but it's
actually an output not an input), but when we added GPIO_HI_Z_OPEN to mean
"open-drain output, pulled low by default", it got too confusing.

This renames those macros to:

  #define GPIO_ODR_HIGH    (GPIO_OUTPUT | GPIO_OPEN_DRAIN | GPIO_HIGH)
  #define GPIO_ODR_LOW     (GPIO_OUTPUT | GPIO_OPEN_DRAIN | GPIO_LOW)

Fixed LM4 still mucking with alternate function settings and levels
even if GPIO_DEFAULT was specified.
