Updates the Servo V4.1 name from 'servo_v41' to 'servo_v4p1'
and the corresponding files and fields. As the VID:PID is
used to identify the device, no other changes are required.
BUG=b:157059356
BRANCH=servod
TEST=Updated the ServoV4.1 from 'servo_v41_v2.0.3735+440cf71e0' to
'servo_v4p1_v2.0.4232-514cb4e92' to verify the servo_updater
supports renames.
TEST=Verified servo_v4p1 manually: Validated console, firmware
update, and servod can connect to the device.

The FROMLIST revision of i2c-pseudo is targeted at the newest Linux
versions, which have new stream_open function and it is preferred for a
pure I/O stream device. However updating to the FROMLIST i2c-pseudo
broke compilation with older kernels that lack stream_open.
Since Linux kernel versions as old as 4.18 are still in common use among
Chrome OS developers, this fixes compatibility by checking for
nonseekable_open and stream_open symbols.
nonseekable_open is only used when stream_open is not found and
nonseekable_open is found. Otherwise stream_open is used.
BRANCH=none
BUG=none
TEST=With Linux 4.18 and Linux 5.2:
$ make
$ # With 4.18 matches nonseekable_open, with 5.2 matches stream_open.
$ strings i2c-pseudo.ko | grep -E -m1 '^(nonseekable_open|stream_open)$'
$ make clean
$ ./install

Changes in this diff:
- Move anprintf() into i2c-pseudo.c.
- Use sizeof_field() instead of FIELD_SIZEOF().
- Add CONST_STRLEN macro for i2cp_cmds[].cmd_size values, because on some
architectures strlen("literal") is not a compile-time constant.
- Use stream_open() instead of nonseekable_open().
- When copy_from_user() returns non-zero, return -EFAULT instead of 0.

Adds the Servo V4.1 to the servo updater as the target 'servo_v41'.
Some minor cleanup was done on the servo_updater logic to make it

the config files directly rather than inferring from the name.

External tools such as platform/dev/contrib/dut-console may import
servo_updater as a module. On import time, this module will check the
existence of FIRMWARE_PATH and potentially raise ServoUpdaterException,
which is unnecessary if the function the importing program calls does
not have reference to the global variable FIRMWARE_PATH (for example,
find_available_version()).
In addition, there is only one function, findfiles(), that is currently
using FIRMWARE_PATH and other similar global variables. Therefore, move
the check for path existence inside findfiles(), so that
ServoUpdaterException will not be raised on module import time.
Also add servo board name constants to servo_updater to reduce duplicate
string literals.

BUG=chromium:1061354
TEST=Run 'sudo servod -b kukui -m jacuzzi' and make sure findfiles() is

RO version is lower than the version in the Cr50 image being
transferred.
With transition to the new RO version, keys and rollback map state,

If the host command handler callback function returns an int, it's easy
to accidentally mix up the enum ec_error_list and enum ec_status types.
The host commands always expect an enum ec_status type, so we change the
return value to be of that explicit type. Compilation will then fail if
you accidentally try to return an enum ec_error_list value.
Ran the following commands and then manually fixed up a few remaining
instances that were not caught:
git grep --name-only 'static int .*(struct host_cmd_handler_args \*args)' |\
xargs sed -i 's#static int \(.*\)(struct host_cmd_handler_args \*args)#\
static enum ec_status \1(struct host_cmd_handler_args \*args)##'
git grep --name-only 'int .*(struct host_cmd_handler_args \*args)' |\
xargs sed -i 's#int \(.*\)(struct host_cmd_handler_args \*args)#\
enum ec_status \1(struct host_cmd_handler_args \*args)##'

Flash log access could be denied in case there is a previously started
log operation in progress.
Flash log by design is a 'the best effort' facility, let's re-try a
few times if Cr50 returns an error when flash log read is attempted.
Also, allow the -L optional parameter to be a decimal value, this is
better aligned with the output format where timestamp is reported as a
decimal value.

There is no need to duplicate short and long option strings in the
.opt and .help_text fields, one is enough.
To properly format --help output in case the command line argument
expects a parameter, part of the .help_text string has to be printed
concatenated with the option strings.
Let's retrieve the short and long option strings form from the .opt
structure and use '%' as the formatting character to allow to indicate
that the the beginning of the help message needs to be printed
concatenated with the option strings.
Also correct the general description.

Standard libc getopt_long() and getopt() functions do not allow the
optional parameters to follow the command line option without the equal
sign ('='), but gsctool utility users expect this form to be
available, so additional processing is done for command line arguments
accepting optional parameters.
This additional processing code is duplicated for each such argument.
On top of that, some arguments which described as requiring the
parameter (not optional) still include code which looks for the
command line option.
Information about expected parameter type is included in the long
options descriptor table, so it is not readily available if the user
specified the short version of the argument in the command line.
To consolidate processing of the optional parameters in one place, in
case the user specified the short version of the command line
argument, the long_opts table is looked up to find the appropriate
long version, then the parameter type is checked, and if the parameter
is supposed to be optional, the next command line token is examined to
determine if this is the optional parameter.

There are a couple of issues with command line processing code:
- command line options must be listed in two different places if we
want to allow both short and long forms of the same argument
- help text for commands is included in yet another place in the code
Indeed, from the libc getopt_long() point of view the long options
table and short options string are completely unrelated: the function
scans the command line arguments vector for -x[x[y]] or --word command
line options style and looks up either short_opts or long_opts
depending on the encountered command line token's style.
The standard way to cross reference long options table and the short
options string is to put the short option character in the long option
table's entries .val field. This is how it is done in gsctool.
What this means is that as long as all short command options are
referenced in the long_opts table, the short command option string
could be generated based no the long_opts table.
The help text and long_opts table would still remain separate and
require manual syncing.
To help with that problem this patch introduces a container structure,
which includes both long option contents and the help text for each
command line option.
This allows to build the long_opts table and then the short_opts
string on the fly, based on the contents of the single table, and also
generated the --help output, ensuring consistency of all
representations.
BRANCH=none
BUG=none
TEST=as follows:
- temporarily added debug code to print out the generated short
option string, got the following:
aBbcd:fF:hIikLMmn:O:oPpR:rS:stUuVvw
which is extended to include previously omitted 'f':
aBbcd:F:fhIikLMmn:O:oPpR:rS:stUuVvw
- verified that 'gsctool -h' outputs before and after this patch are
the same apart from including help text for -B
- verified that it is still possible to update a Cr50
- verified --board_id/-i command with various optional parameter
representations.

Add a serial number arg that can be used to specify which CCD device to
use. If there are multiple CCD devices, you can use this arg to pick
which device to update.
BUG=none
BRANCH=none
TEST='gsctool -f -n $SERIAL' can be used to get the cr50 version from
two chromebooks connected to the same machine. 'gsctool -f' still works
too.

As of pexpect 3.0, the fdexpect module was moved into the pexpect
package. Prior to 4.0, a wrapper module was installed along with
pexpect, so "import fdexpect" continued to work. In 4.0 this wrapper
was removed.
Importing fdexpect from pexpect works for our current pexpect 3.3, and
will continue to work when we update pexpect to 4.0+.

When both RO and RW updates are required, and the RO includes a new RW
signing key, to ensure recovery from failed updates, the RW section of
the image needs to be updated before the RO section,
In this case interrupted RO or RW update will result in the H1
rebooting still using the original RO and original RW.
If the RO was updated first and the RW update was interrupted, the
chip could end up with the newer RO with no RW to verify with the new
key.
BRANCH=none
BUG=b:74100307
TEST=created an image with fake RO_B version number of 0.0.106, and
then tried to update to this image. Observed that RW_B was

We should ensure that all custom task definition are non-zero and fit
with the globally defined events. Add compile time check and change
semantics to specify bit number (instead of making all callers use the
BIT macro).
This also fixes an error with TASK_EVENT_PHY_TX_DONE for ITE being 0.
The bug that made that happen hasn't landed on any firmware branches
that use it though.

The script now unconditionally attempts to (re)install the module, even if
it is already loaded. (This also removes a message which had a typo,
mistakingly referring to i2c-dev instead of i2c-pseudo.)
The script no longer attempts to load i2c-dev, since servod does that now.
The script now runs "make clean" before "make" .
The header comment no longer references a section of the README that was
never checked in.
BRANCH=none
BUG=b:79684405
TEST=I ran the install script in various scenarios:
1) No i2c-pseudo module loaded or installed.
2) i2c-pseudo module loaded but not installed.
3) i2c-pseudo module installed but not loaded
4) i2c-pseudo module loaded and installed.
In all cases the module was (re)installed and either left loaded
(if applicable), or loaded (if not previously loaded).
The script does not attempt to unload and re-load the module when
re-installing only for simplicity.

This Linux kernel module provides I2C adapters that can be backed by
userspace programs. This allows for userspace implementations of
functionality such as tunneling I2C through another communication channel
to a remote I2C bus.
BRANCH=none
BUG=b:79684405
TEST=Used i2c-tools CLI to i2c-dev to issue I2C queries, and Python
interactive interpreter as the I2C pseudo adapter controller. The
i2c-pseudo module correctly proxied write, read, write+read, and multi-byte
reads through the controller character device, and it correctly proxied
back the responses from the character device, including the specific byte
values read. Later, I implemented an I2C pseudo controller in Servod and
used it to flash an ITE EC over I2C using both Servo Micro and Suzy-Q.
