This feature is inconsistent. Not all boards have such a symlink
(for a obvious reason).
This feature is fragile. It's most likely not tested and going to be
broken if not already. Developers won't like it if they have to test
two different ways to build boards before submitting patches.
This feature is not necessary. If you build EC in the standard way
(e.g. make BOARD=samus), these symlinks are not needed.
This feature is wasteful. Extra disk spaces are used and extra lines
are added to Makefile (increasing code complexity slightly).

With commit e9883124ff16, a GPIO_INT macro was added. That change
also required that all instances of GPIO_INT in a board's
gpio.inc file come before any GPIO macros, or the interrupt
handler wouldn't work properly.
This CL just adds a warning comment about requirement to all
gpio.inc files.

Some chips previously defined CONFIG_I2C and others didn't. Standardize
the usage by removing CONFIG_I2C from all config_chip files and force it
to be defined at the board level. Also, make boards define
CONFIG_I2C_MASTER and/or CONFIG_I2C_SLAVE based on the I2C interfaces
they will use - this will assist with some later cleanup.

In the gpio_info struct, we had a irq_handler pointer defined even
though a majority of the GPIOs did not have irq handlers associated. By
removing the irq_handler pointer out of the struct, we can save some
space with some targets saving more than others. (For example, ~260
bytes for samus_pd).
This change also brings about a new define:
GPIO_INT(name, port, pin, flags, signal)
And the existing GPIO macro has had the signal parameter removed since
they were just NULL.
GPIO(name, port, pin, flags)
In each of the gpio.inc files, all the GPIOs with irq handlers must be
defined at the top of the file. This is because their enum values from
gpio_signal are used as the index to the gpio_irq_handlers table.

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.

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

generate both the gpio_signal enum and the gpio_list array.

In board.c, we initialize this struct:
struct i2c_port_t {
const char *name; /* Port name */
int port; /* Port */
int kbps; /* Speed in kbps */
};
extern const struct i2c_port_t i2c_ports[];
The port field refers to the physical I2C bus on the EC.
Meanwhile, in board.h, we've identified the bus where each I2C device is
attached:
Up until this CL, we've been picking one of those device-to-bus macros to
initialize port fields of the i2c_ports[] array. That's wrong and confusing.
This change specifies the physical channel with the physical number.

This is tidier than every board defining its own module_id enum, and
encourages standard naming of modules.
A subsequent CL will do more cleanup (standardizing on MODULE_LED
instead of MODULE_POWER_LED and MODULE_LED_KIRBY), but it's easier to
do that as a separate CL than part of this one.

We only used I2C_PORTS_USED to iterate through the list of hardware ports
actually in use, but we defined it in board.h at the same place where we
matched particular I2C devices to the (possibly shared) buses they're on.
This CL makes I2C_PORTS_USED into a global constant, so it can be set
automatically where we initialize the ports, and doesn't have to be
related to the list of attached devices.

The BOOTCFG register configures a couple of important things: whether to
allow jumping into the builtin ROM bootloader at reset, and whether or not
to allow JTAG access for programing and debugging.
The default is "no" and "yes". But the BOOTCFG register can be locked so
that it can't be changed again, which means that if the wrong values are put
into it, the system is pretty much bricked.
On Link, we wrote a BOOTCFG value that allowed a GPIO to be used as a bypass
to optionally trigger the ROM bootloader, but on Slippy and its derivatives
that GPIO is not pulled up. If you program the Link values into BOOTCFG on a
Slippy, the system is stuck in the ROM bootloader more or less forever.
This change disables that GPIO, keeps JTAG enabled, and locks those settings
for all LM4 chips (it's a chip config now, not a board config). We've never
actually used the GPIO to invoke the ROM bootloader, but we have managed to
brick a number of systems just by having it enabled, so we're going to lock
it into a safe configuration now.

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.

Slippy uses UART2 instead of UART1 and so the EC needs
to be able to tolerate having the host use a different
interface. There are of course many ways to accomplish
that but this approach adds two config variables to specify
the host uart and the host uart irq.
The UART port setup is split out to allow them to be
configured separately rather than needing to be adjacent
in a for loop.
The interrupt functions were renamed (to ec and host) in
order to indicate which interface they are responsible for.

This changes current TASK() syntax to TASK_BASE() and TASK_NORMAL(),
where TASK_BASE is necessary for the EC to boot on a board and
TASK_NORMAL represents the task that can be removed in a test binary.
Tasks introduced by a test should be listed as TASK_TEST().
Note that this CL breaks current tests (many of them are broken anyway),
which will be fixed in up coming CLs.

Rename tasks
TICK -> HOOKS
The hooks task handles more than just the TICK hook now.
X86POWER -> CHIPSET
GAIAPOWER -> CHIPSET
Kinda kludgy that the name of the task controls which chipset source gets
included. Change this to a CONFIG_CHIPSET_{X86,GAIA} #define to make it
easier to support future chipsets. Also, rename the task function to
chipset_task() so ec.tasklist is chipset-agnostic.
No code changes, just renaming constants and functions.

Increase stack size slightly for vboot hash task since the vboot
SHA256 function allocates ~300 bytes of stack data. Reduce stack size
for watchdog, power LED, and a few other tasks with simple call trees

reduced stack.

Superseded by EC software sync (hash-based).
Sig-based vboot was correctly implemented, but ended up being too slow
to be useful given the limited processing power of the EC chips, and
we also couldn't come up with a manageable way to handle A/B
autoupdate of signed EC firmware.
This change and an associated vboot_reference change shrinks the EC
binary by ~2KB.
