Opt for 7bit slave addresses in EC code. If 8bit is
expected by a driver, make it local and show this in
the naming.
Use __7b, __7bf and __8b as name extensions for i2c/spi
addresses used in the EC codebase. __7b indicates a
7bit address by itself. __7bf indicates a 7bit address
with optional flags attached. __8b indicates a 8bit
address by itself.
Allow space for 10bit addresses, even though this is
not currently being used by any of our attached
devices.
These extensions are for verification purposes only and
will be removed in the last pass of this ticket. I want
to make sure the variable names reflect the type to help
eliminate future 7/8/7-flags confusion.

All 4 I2C ports on the Sweetberry were configured at 800 KHz. 3 of the I2C
ports are limited to 400 KHz and the FMP I2C port can be up to 1 MHz. This
means that 3 of the slower speed I2C ports are out of spec by a factor of
two. Traces of the rails showed that the rails were still functioning at
800 KHz, although the FMP I2C rail is actually at 896 KHz. The STM32F4
Reference Manual Rev4 does not indicate which potential problems occur
when operating in this condition.
The I2C speeds were adjusted to match spec with the 3 slow speed ports set
to 400 KHZ. The I2C prescalers for the FMP I2C port do not have a suitable
1 MHz configuration at our system clock speed so the FMP I2C rail was
adjusted to 900 KHz to match the measured speed within 2% for all rails.
The cost of this change is the scan time for a group of 28 INA's increased
from 4.9 ms to 5.5 ms.

It's simply a bad idea to describe a macro in multiple locations.
It'll make it hard to change. It'll be difficult to keep all
locations in sync.
This patch replaces the comment duplicated in all ec.tasklist with
a pointer to the CONFIG_TASK_LIST definition. The macro will be
described in a single place (just like all/most other macros).

Rename i2c_xfer to i2c_xfer_unlocked. Audit all users of i2c_xfer to
see if they can use simple locking semantics or require their own
locking. Since locked accesses are only safe for I2C_XFER_SINGLE
transactions, remove the flags parameter from i2c_xfer. This also makes
the audit a bit easier.
Some remaining applications hold the bus locked across several
transactions that would otherwise be atomic, and a few others implement
complex I2C transactions in multiple commands.
Add a (nondeterministic) verification on the I2C port locking
correctness. This will catch all statically incorrect locking patterns,
although dynamically incorrect locking patterns may not be caught.
Related: Revise the i2c_port_active_count to be a bitmap of the active
ports instead of a count of the active ports. The EC's mutex does not
provide an is_locked() primitive, and we would prefer not to have one.
