u-boot has a standard "serial#" environment variable that is suitable for storing the iSerial number we will supply via the USB device descriptor. serial# is automatically picked up by the disk subsystem in u-boot - thus providing a handy unique identifier in /dev/disk/by-id as detailed below. Storing the hardware serial identifier in serial# means we can change the serial# if we want before USB enumeration - thus making iSerial automatic via OTP but overridable if necessary. This patch reads the defined OTP fuse and sets environment variable "serial#" to the value read. With this patch in place the USB mass storage device will appear in /dev/disk/by-id with a unique name based on the OTP value. For example /dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0:0 Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Cc: Fabio Estevam <fabio.estevam@nxp.com> Cc: Rui Miguel Silva <rui.silva@linaro.org> Cc: Ryan Harkin <ryan.harkin@linaro.org> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com>
