Say Y here to get to see options for platform support for

space through sysfs interface. The sets of registers for sysfs access
|
are defined per system type bases and include the registers related
|
to system resets operation, system reset causes monitoring and some

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
|
device driver to do necessary initial swap of the boot partition.
