Subject: [PATCH -next 07/14] kddv/cmd: Add command to create/remove mockup device
From: Zhang Xiaoxu <zhangxiaoxu5@...wei.com>
Add command kddv.cmds.mock to create/remove mockup device which support
by the test framework. Usage:
Create device:
$ python3 -m kddv.cmds.mock --bus spi --devid mchp23k256
create spi device mchp23k256 success!
Then the mockup device can be accessed by exists user space tools.
$ ls /dev/mtd0
mtd0 mtd0ro
$ hexdump /dev/mtd0
0000000 0000 0000 0000 0000 0000 0000 0000 0000
*
0008000
Remove the mockup device:
$ python3 -m kddv.cmds.mock --bus spi --devid mchp23k256 -r
[ 198.718172] Deleting MTD partitions on "spi0.0":
remove spi device mchp23k256 success!
