The build system includes a bunch of files into verstage that
also exist in romstage - generic drivers etc.
These create link time conflicts when trying to link both the
verstage copy and romstage copy together in a combined configuration,
so separate "stage" parts (that allow things to run) from "library" parts
(that contain the vboot specifics).

It became necessary to indicate the beginning of the normal boot
process. This patch adds a new pattern, a slow (over 2 seconds) fade
in into the 0, 87, 155 color.

Modify colors as suggested by product review folks. This is not final,
to make it easier to identify RGB locations in the hex dumps, express
their values in decimal as opposed to hex.

The originally loaded blinking program was written to allow gradual
change in LED brightness, which required controlling each LED with its
own engine. In fact there is no need in gradual brightness changes
when the firmware is controlling the ring. This allows to control all
LEDs by one engine, making the code simpler and more robust (no need
to synchronize the three engines any more).

The two controllers on the ring are programmed independently, and if
the second controller is running the old pattern while the first one
was loaded with a new pattern, there is a window of when the two
unrelated patterns might interact.
To avoid this shut down execution on both controllers before starting
downloading the new pattern code.

Add compiled lp55231 code snippets to allow display certain patterns
when booting the device with the recovery button pressed.
As soon as the press is detected, the low intensify solid white
pattern is enabled. Holding recovery button long enough causes the
device transition between the wipeout requested and recovery requested
states, with the appropriate changes in the displayed pattern.
The patch also includes the source code for the LED controller as well
as instructions on how to compile and modify the code to result in
different colors, intensities, blink periods and duty cycles.

The patterns displayed on the LED ring while under the coreboot
control are not driven by the vboot, but by the board code instead,
The four distinct states of the LED display are:
- all off
- recovery button push detected, waiting for it to be released
- wipeout request pending - recovery button was pushed long enough
to trigger this request
- recovery request pending - recovery button was pushed long enough
to trigger this request.

When in development environment, some SP5 devices might not have the
LED ring attached. They are still fully functional, but when booting
up are generating massive amount of i2c error messages. This patch
prevents accesses to non-existing lp55321 devices.
When loading the program into the device the vendor recommends 1 ms
delay when accessing the program control register. This patch
separates these accesses into a function and add a delay after every
access.
Another fix - advance the program address when loading multipage
programs.
Set the global variable register 3c, not used by coreboot programs, to
a fixed value. This will allow depthcharge to avoid re-initializing
the controller when not necessary.
BRANCH=storm
BUG=chrome-os-partner:36059
TEST=booted firmware on an SP5 with no LED ring attached, no excessive
error messages are generated, saw the default pattern displayed
when the recovery button is pressed during reset.

This is a copy of the depthcharge ww ring driver implementation ported
into coreboot. The main differences are:
- direct use of the i2c driver instead of using the callback driver
description
- no dynamic memory allocation for the controller structures
BRANCH=storm
BUG=chrome-os-partner:36059
TEST=with the rest of the patches applied the LED ring gets
initialized to the default pattern at coreboot start.
