Liming Sun 79e29cb8fb 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.
