| 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. |
