platform/mellanox: Add TmFifo driver for Mellanox BlueField Soc This commit adds the TmFifo platform driver for Mellanox BlueField Soc. TmFifo is a shared FIFO which enables external host machine to exchange data with the SoC via USB or PCIe. The driver is based on virtio framework and has console and network access enabled.

platform/mellanox: mlxreg-hotplug: Modify to use a regmap interface Restructure mlxreg header for unification of hotplug item definitions. Unify hotplug items to allow any kind of item (power controller, fan eeprom, psu eeprom, asic health) in common way. Use a hardware independent regmap interface, enabling the support of hotplug events over programmable devices attached to different bus types, such as I2C, LPC, or SPI.

platform/mellanox: Introduce support for Mellanox register access driver Introduce new Mellanox platform driver to allow access to Mellanox programmable device register space trough sysfs interface. The driver purpose is to provide sysfs interface for user space for the registers essential for system control and monitoring. The sets of registers for sysfs access are supposed to be defined per system type bases and include the registers related to system resets operation, system reset causes monitoring and some kinds of mux selection.

platform/mellanox: Add bootctl driver for Mellanox BlueField Soc This commit adds the bootctl platform driver for Mellanox BlueField Soc, which queries secure state and controls the eMMC boot partition swapping by sending SMC calls to ATF running at EL3. Below are the sequences of typical use case. 1. User requests boot partition swapping, which could be on-demand or during boot-image upgrade via UEFI capsule; 2. This bootctl driver handles the request and sends SMC call to ATF. ATF programs register BREADCRUMB0 which has value preserved during warm reset. It also programs eMMC to swap the boot partition; 3. After software reset (rebooting), ATF BL1 (BootRom) checks register BREADCRUMB0 and enable watchdog if configured; 4. If booting fails, the watchdog timer will trigger rebooting. In such case, ATF Boot ROM will switch the boot partition back to the previous one. This is a robust feature and used to prevent failure during boot partition upgrade.

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.
