^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) * Cavium Octeon & ThunderX MMC controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) The highspeed MMC host controller on Caviums SoCs provides an interface
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) for MMC and SD types of memory cards.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Supported maximum speeds are the ones of the eMMC standard 4.41 as well
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) as the speed of SD standard 4.0. Only 3.3 Volt is supported.
