MA-9116 - [IOT] iot-flashall-imx6ul.sh some times blocked
after flash "gpt" partition.
The issue occurs when slot is ok but gpt partiton is damaged.
After "fastboot flash gpt", the partition table in memory still
has just two entries(gpt and bootloader).
When run "fastboot reboot bootloader", the command should write to
the "misc" partiton. But no entry in the partition table in memory.
After "fastboot flash gpt", Re-load the partition table to memory
can fix it.
