31	  This driver allows access to Mellanox programmable device register
32	  space through sysfs interface. The sets of registers for sysfs access
33	  are defined per system type bases and include the registers related
34	  to system resets operation, system reset causes monitoring and some
35	  kinds of mux selection.

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