error getting mtd part number: $part

get_mtd_biggest_part for $DEVICE_TYPE: Backtrace :: $PARTITION ::

Error when trying to find mtd part range

一路追踪：

1. part=`get_mtd_partition_number.sh "nor"` || die "error getting mtd part number: $part"
2. in get_mtd_partition_number.sh  PARTITION=`get_mtd_biggest_part $DEVICE_TYPE` || die "get_mtd_biggest_part for $DEVICE_TYPE: Backtrace :: $PARTITION :: "
3. in mtd_common.sh  PART_RANGE=`find_mtd_part_range "$DEVICE_TYPE"` || die "Error when trying to find mtd part range"
4. in mtd_common.sh  find_mtd_part_range() {......
           TYPE=`find_part_type $PART`
       
5. in mtd_common.sh     find_part_type() {
     PART=$1
     MTD_DEV="mtdblock$PART"
     if [[ -e /sys/class/mtd/mtd$PART/type ]]; then
       TYPE=`cat /sys/class/mtd/mtd$PART/type`
       if [[ $TYPE == 'nand' ]]; then
         PART_TYPE='nand'
       else
         if [[ `ls /sys/class/mtd/mtd$PART/device/driver/ | grep 'flash'` ]]; then
           PART_TYPE="nor"
         elif [[ `ls /sys/class/mtd/mtd$PART/device/driver/ | grep 'qspi'` ]];then
           PART_TYPE="qspi"
         elif [[ `ls /sys/class/mtd/mtd$PART/device/driver/ | grep 'ospi'` ]];then
           PART_TYPE="qspi"
         elif [[ `ls /sys/class/mtd/mtd$PART/device/driver/ | grep 'spi'` ]];then
           if [[ `cat /proc/mtd |grep -E "mtd$PART |mtd${PART}: "|grep -i qspi ` ]];then
             PART_TYPE="qspi"
           else
             PART_TYPE="spi"
           fi
         else
           die "/sys/class/mtd/mtd$PART/device/driver doesn't exist"
         fi
       fi
     else
       die "/sys/class/mtd/mtd$PART/type doesn't exist"
     fi
     echo $PART_TYPE
   }

TYPE=`cat /sys/class/mtd/mtd0/type`

TYPE=nor

ls /sys/class/mtd/mtd0/device/driver/

bind  e2000000.nor  uevent  unbind

mtd_common.sh

所以grep 'flash'要改为 grep 'nor'

 if [[ `ls /sys/class/mtd/mtd$PART/device/driver/ | grep 'nor'` ]]; then

因为build-in driver

所以将blk_device_prepare_format.sh
