0064 The Mellanox BlueField firmware implements functionality to
0065 request swapping the primary and alternate eMMC boot partition,
0066 and to set up a watchdog that can undo that swap if the system
0067 does not boot up correctly. This driver provides sysfs access
0068 to the userspace tools, to be used in conjunction with the eMMC
0069 device driver to do necessary initial swap of the boot partition.
