This patch adds very basic minimal support for the Marvell Octeon 3 CN73xx based EBB7304 EVK. Please note that the basic Octeon port does not support DDR3/4 initialization yet. To still use U-Boot on with this port, the L2 cache (4MiB) is used as RAM. This way, U-Boot can boot to the prompt on this board. Supported devices: - UART - reset - CFI parallel NOR flash Signed-off-by: Stefan Roese <sr@denx.de>
