[PATCH 03/21] imx9: soc: Serial No align with rom setting

[Peng Fan (OSS)]

From: Frank Li <Frank.Li at nxp.com>

ROM use UID[0] and UID[1] as serial number with big endian when usb serial
download.

After update this, uuu(>1.6) can use below command to filter out devices
when multi boards connected.

uuu -ms <serial#> ...

[sudo] uuu -lsusb can list known devices with serial# informaiton.
