The recent addition of the multicomponent version string for cr50,
requires further tweaking of the version generating script. In
particular, the CROS_EC_VERSION32 variable used by the "verson" cli
command is not supposed to include any information about subcomponents
of the image, it should reflect the EC version only.
Separating everything after the first space accomplishes that.

The timer test checks the accuracy of the internal timer. After sync,
DUT and TH start counting down one second. After one second, DUT raises
GPIO level. TH determines whether the test passes or not based on how
much more or less time elapsed than one second, assuming its clock is
calibrated.
This test takes advantage of TH running on a bare chip. If the host
were measuring (instead of TH), the timing would be affected by many
software and hardware layers (e.g. UART drivers on DUT and host,
python interpreter, etc.).

for cr50 the array is extended with the three other components.
This patch also allows to change the 'tree dirty' marker appended to

Using the USB SPI endpoint may require doing a bunch of transactions

This change postpones the reset until we're done using the usb spi

The function returns a two element string, the version information and

Cr50 was not waking up long enough after SPS_CS_L was asserted for the
spi slave transactions to start and disable sleep. It also was not
handling SYS_RST_L properly when it was asleep.
This change sets SPS_CS_L to be an edge triggered wake up source instead
of level triggered, because cr50 should just wake up on the edge and
disable sleep until the spi transaction is done.
It also adds sys_rst_l as a wakeup source. The sys_rst_asserted
interrupt cannot be triggered while cr50 is asleep, so the
pmu_wakeup_interrupt will call sys_rst_asserted if SYS_RST_L is low at
resume. This change relies on the EC extending the delay in

The FUSB302A had silicon limitation that required using its
autodetect logic when presenting as a SRC. While testing on
Kevin/Gru and connecting PD dongles, observed issues where
following successful connects, the USB PD state machine would
remain in SRC_DISCONNECTED state after removing the dongle.
Flipping the connector (to reverse polarity) will recover from
this stuck state.
In order to resolve this problem and to make the tcpm_get_cc()
FUSB302 driver function more consistent with the USB PD protocol
state machine while acting as a source, the autodetect feature
is now only used when a revA silicon device is detected.
If it's not revA, then full manual mode is utilized for tcpm_get_cc.
In addition, a new measure_cc_pin_source funciton was added

A recent cr50 loader modification introduced a counter in a scratch
register which is incremented on every startup. The idea is that valid
RW would decrement the counter, signaling that the start was
successful.
Should the counter exceed the value of 5, the loader assumes that the
RW being started is not fit to run, and picks the older RW to run, if
available.
This patch adds a function to process the startup retry counter.
First of all the counter is zeroed, as this function is supposed to be
called only once the RW run is considered successful and reliable.
Then the current situation is examined. If the counter value read from
the scratch register exceeds 5 AND running image is not the newer of A
and B, it is considered an indication of a fallback from a bad newer
image.
To prevent the newer image from being considered a contender on the
following startups, its header is corrupted.

would cause the new function to be called soon after boot.
built a new image and installed it on the debug board. Then
modified the image to throw an exception early in the boot up
sequence, and installed it as a newer image on the debug board.
Observed the debug board restart the new image several time and
then fall back to the older image, printing the following on the
console:
system_process_retry_counter:retry counter 7
corrupt_other_header: RW fallback must have happened, magic at 44000 before: ffffffff
corrupt_other_header: magic after: 0
The following restarts start the older image without trying to run
the failing newer image.

The SoC looks for two RO images at reset, and is typically
configured for two RW images as well. This CL reports version
strings for all those images, as well as identifying the active
RO and RW copies.
Since the RO image doesn't contain a version string, we create
one using the epoch_, major_, minor_, and img_chk_ members of its
signed header.
BUG=chrome-os-partner:55558

TEST=make buildall; run on Cr50 hardware
The "version" command now includes information like this:
RO_A: * 0.0.2/a3c3d5ea
RO_B: 0.0.2/8895c9eb
RW_A: cr50_v1.1.4965-a6c1c73-dirty
RW_B: * cr50_v1.1.4959-2f49d5c
The '*' indicates the active image.
The test/tpm_test/tpmtest.py program has been updated to request
the version information at startup, and it also now reports
similar information, just all on one line:
RO_A:* 0.0.2/a3c3d5ea RO_B: 0.0.2/8895c9eb RW_A: cr50_v1.1 ...
The active images are marked with a '*' following the ':', so
that the same regexp can match either format:
($ro, $rw) = m/RO_[AB]:\s*\*\s+(\S+).*RW_[AB]:\s*\*\s+(\S+)/s;

Rohm suggests setting VSYS to the higher value during precharge and only
setting it to the lower voltage after we have crossed the lower voltage.
Note that the VSYS register also controls the pre vs fastcharge
