BDS has been slowly rotting as we make changes for Link. I haven't been able to test the BDS image for some time (I think due to openocd updates that no longer like the BDS configs), and now it doesn't even compile. This is gating the Link schedule, so I'm just turning it off. If we ever need the BDS again, well, what fun. BUG=none TEST=none It already doesn't work, so it should continue to not work.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

Build Options
=============
- CONFIG_WATCHDOG_HELP
Try to detect a watchdog that is about to fire, and print a trace.
This is needed on STM32, where the independent watchdog has no early
warning feature and the windowed watchdog has a very short period.
- CONFIG_PANIC_NEW_STACK
When reporting a panic, change to a completely new stack. This might
help get a useful trace out a situation where the stack or stack
pointer has been corrupted.
- CONFIG_PANIC_HELP
Report extra information about a panic, such as the fault address,
here shown as bfar. This shows the reason for the fault and may help
to determine the cause.

- CONFIG_ASSERT_HELP
Report assertion failures in a vebose manner to aid debugging. When
enabled an ASSERT() which fails will produce message in the form:
ASSERTION FAILURE '<expr>' in function() at file:line
