有的，乐鑫官方有一个AT over SPI.

[ 1.124750] Creating 7 MTD partitions on "spi0.0":

[ 1.175241] 0x000000d20000-0x0000010f7e00 : "UDISK"
[ 1.181242] mtd: partition "UDISK" extends beyond the end of device "spi0.0" -- size truncated to 0x2e0000
tina配置的分区中并没有UDISK,但是在打包过程中,update_mbr这个工具,手动附加了一个UDISK分区.
请问这个分区有什么用处?
