- The Mellanox BlueField firmware implements functionality to
- request swapping the primary and alternate eMMC boot partition,
- and to set up a watchdog that can undo that swap if the system
- does not boot up correctly. This driver provides sysfs access
- to the userspace tools, to be used in conjunction with the eMMC
