DOC = """
This test replaces chip (i.e. TCPC) firmware on the DUT's bios.bin
and reboots into it.  The expectation is that the TCPC firmware
is updated correctly when the system boots with the updated bios.bin

Software sync applies the TCPC firmware update and verifies that
it has been applied.  If the DUT rebooted successfully, we know
that the test has passed.

For independent verification, the firmware_CompareChipFwToShellBall
FAFT test can be used to verify the running TCPC firmware versions.

For complete testing, this test needs to be invoked to downgrade, then
upgrade the TCPCs so that we have confidence that the update process
really happened.
