Previously the version string was special cased in the USB stack
because the build system prevented the inclusion of ec_version.h in
any file other than common/version.c. This lead to common/version.c
being the only place that the USB version string could be computed
and thus the special case of filling in the version string descriptor
at run time. This made the USB stack more complex, and lead to the
common/version.c file including usb.h, which is actually STM32
specific.
Now, the portion of ec_version.h that is deterministic is only
updated when something in the tree actually changes (by way of a
conditional in the makefile), and ec_version.h no longer has to
depend on all object files (other than the special version.o).
This allows anyone to include ec_version.h as needed. In particular,
each board that wants to define a USB version string can directly
include ec_version.h and do so.

The original algorithm is given in the TMP006 User's Guide
(SBOU107.pdf). The algorithm we previously implemented is that,
plus some additional and completely undocumented massaging of the
Tdie and Vobj registers. The original meaning of that hack is now
lost in the mists of time, thanks to our email retention policy.
This CL introduces a new algorithm variant, but at least this
time the details are in the bug report. It's essentially the same
as the User's Guide algorithm, except that we apply one-stage FIR
filters to the Tdie input and the Tobj output.
There are five new parameters: d0, d1, ds, e0, e1. Refer to
tmp006_read_object_temp_k() in ec/driver/temp_sensor/tmp006.c to
see how these new parameters are applied.
CAUTION: The tmp006 sensor algorithm is mostly math and magic
numbers. The spreadsheet attached to the bug report has six
sheets with wildly varying values for those parameters. Since the
correct parameter values haven't yet been determined for Samus,
all I can be sure of with this CL is that it seems to work and
isn't any worse than the old one.
Oh, and note that the EC's 't6cal' console command has been
disabled until/unless we add support for floating point IO. Use
ectool from the host to get and set the params instead.

PD accessories that are RW update-able will broadcast their rw_hash
SHA1 digest upon connection to the PD MCU which will store it.
For update purposes, the host needs that accessories device id and
rw_hash to determine its proper firmware update payload.
This CL creates a host command that requests the type-C accessory info
attached to a particular port. It also implements an ectool command
to expose the host command.

PD accessories that are RW update-able will broadcast their rw_hash
SHA1 digest upon connection and remain in RO briefly for a response.
In order to speed-up the response and decouple common case of
accessory is up-to-date, the PD MCU will keep a small 4 entry table of
PD accessory device ids and their corresponding RW hashes for quick
lookup.
The AP will be the source of new updates and their corresponding
device id's and RW hashes and therefore needs a method to update the
PD MCU table.
This CL creates the table, host command & ectool command to facilitate
future driver / daemon to update the RW hash entries.

Current ectool uses max outsize / insize from protocol v2
even if we have a v3 protocol ec. This makes some command
not working when actual size supported by ec is less than
max size from protocol v2.
This CL uses protoinfo command to read max size from ec
during the initialization process to correctly set max size
for ec with protocol v3+. For ec with protocol v2, protoinfo
command won't exist, hence ectool won't modify the max size
and used the size that we set when init the protocol.

This adds a new host commmand for sending RW updates to PD devices.
The host command has a variety of sub-commands for performing the
update, including: erase RW, reboot, write new hash, write flash.
To program zinger RW, you should send host commands in this order:
write new hash to all 0's
reboot (zinger boots into RO since RW hash doesn't match)
erase RW
write flash
write new hash to match contents of RW
reboot
This also adds an ectool command to write a new RW. Just pass it
the RW .flat or .bin file.

The original version of the script worked but as the USB PD protocol
SM has been enhanced to handle more complicated scenarios the
occurrence of collisions on the baseband comm has grown and script
needs to account for that.
Script now checks status of ACK from zinger 'DONE 0' and retries two
additional times for commands that failed. If those three attempts
are unsuccessful script raises exception and quits.
Also added some more logging around retries and progress of chunk
writes.
