     328The following kernel configs should be enabled for the OCTEON-TX CN80XX / CN81XX:
     329* SERIAL_AMBA_PL011 - ARM SBSA UART
    329330* MMC_CAVIUM_THUNDERX - MMC
    330331* EDAC_THUNDERX - Error Detection and Correction (works with 'edac-util' app from 'edac-utils' package)
     
    339340* PCI_HOST_THUNDER_ECAM - Enhanced Configuration Access Mechanism for PCIe memory mapped I/O
    340341* ARM_SBSA_WATCHDOG - ARMv8 Watchdog
     342* CRYPTO_DEV_CAVIUM_ZIP - Hardware Compression / Decompression off-load
     343* HW_RANDOM_CAVIUM - Hardware accelerated random number generator
     344
     345Note that there are many kernel drivers using the name 'Octeon' but they typically refer to a different chipset and the CN80XX / CN81XX have more in common with the Cavium 'ThunderX' architecture as that is the SoC core.
