realtek_mst_i2c_spi.c: Introduce ISP enter param
This is needed to avoid attempt entering ISP mode multiple
times. The ISP mode can only exit after a reset, so once the
reset MCU parameter is set to 0, the device will not able to
exit from ISP mode and hence …
[View More]shouldn't enter ISP again on
the next operation.
Without exit ISP mode, the device data, like firmware version,
will not show the correct value, this param will also help
to identify this situation.
Example on update a firmware with A/B udpate:
flashrom -p realtek_mst_i2c_spi:bus=x,reset-mcu=0,enter-isp=1 write fw
flashrom -p realtek_mst_i2c_spi:bus=x,reset-mcu=0,enter-isp=0 write flag
-> then either reset computer to allow update to take effect, or:
flashrom -p realtek_mst_i2c_spi:bus=x,reset-mcu=1,enter-isp=0 command
to trigger the update.
