On some chips, the full erase operation can take really long:
e.g 13s for 2MB mass-erase on the STM32H7x3 family.
Add a new mechanism retrying the ACK detection rather than extending
the default timeout which would imply very slow behavior in other cases
(e.g. connection).

If a bios carries an EC image signed by a wrong key, EFS EC falls back
to the previous slot upon reboot. Vboot currently does not handle this
case and tries to update the EC with an incompatible image again.
When this happens, a user sees 'applying critical update' screen
repeatedly.
This patch adds EFS_VERIFYV host command. Vboot on AP calls it to check
whether the EC likes a newly updated image or not. If the verification
fails, it's considered as update failure and vboot displays 'broken'

This adds the driver for the SB-TSI temp sensor.
This is a sensor on the AMD AP SOC (Stoney Ridege FT2) that acts like an
8-pin temp sensor with an I2C interface.

This CL adds scripts to support updating ec image to the SPI flash by
UUT(UART Update Tool) for npcx ec. A new array BOARDS_NPCX_UUT is
introduced to include the board name which will use the UUT mechanism.
The detail of test setup/procedure is listed below:
1. Connect the following singals between npcx7 evb and Servo board v2.
NPCX7 EVB Servo V2
---------------------------------------
GPIO64/CR_SIN <--> UART1_SERVO_DUT_TX
GPIO65/CR_SOUT <--> UART1_DUT_SERVO_TX
VDD_3.3V <--> PPDUT_UART1_VREF
2. Manually pull the UUT mode strap pin(GPIO65/CR_SOUT) to ground with a
10 KOhm resistor.
3. Assert a EC VCC1_RST reset or issue a Power-Up reset.
4. Remove the pull-down in step 2.
5. Move npcx7_evb from array BOARDS_NPCX_7M6X_JTAG to BOARDS_NPCX_UUT in
flash_ec.
6. ./util/flash_ec --board=npcx7_evb.
BRANCH=none
BUG=none
TEST=Follow the steps above. Dump the SPI flash content to a file via
JTAG. Compare the file and ec image. Make sure their content is all
the same. Check the ec can reboot after programming.
Run "sysjump rw"; make sure RW image works well.

Add espi_signal_is_vw in new file common/espi.c for
testing if a signal is an eSPI virtual wire. API used
in power common and intel_x86.
Fix CONFIG_BRINGUP support for eSPI (off by default).
Add espi_vw_get_wire_name returning a pointer to
constant string. Chip modules do not need to maintain
names of eSPI signals.

Because Scarlet doesn't use smart battery, in the current
implementation of charging algorithm, we simply provide constant
voltage/current to the battery.
However, the datasheets of Scarlet battery packs do state different
desired voltage/current in different temperature range.
So we should implement the custom charging profile for the battery.
