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 at denx.de> --- Changes in v4: - Remove CONFIG_BOARD_SIZE_LIMIT Changes in v3: - Remove inclusion of "common.h" - Slightly change some copyright messages (adjust year) Changes in v2: - Removed CONFIG_SYS_MIPS_TIMER_FREQ arch/mips/dts/Makefile | 1 + arch/mips/dts/mrvl,octeon-ebb7304.dts | 96 ++++++++++++++++++++++++ arch/mips/mach-octeon/Kconfig | 14 ++++ board/Marvell/octeon_ebb7304/Kconfig | 19 +++++ board/Marvell/octeon_ebb7304/MAINTAINERS | 7 ++ board/Marvell/octeon_ebb7304/Makefile | 8 ++ board/Marvell/octeon_ebb7304/board.c | 9 +++ configs/octeon_ebb7304_defconfig | 37 +++++++++ include/configs/octeon_common.h | 19 +++++ include/configs/octeon_ebb7304.h | 20 +++++ 10 files changed, 230 insertions(+) create mode 100644 arch/mips/dts/mrvl,octeon-ebb7304.dts create mode 100644 board/Marvell/octeon_ebb7304/Kconfig create mode 100644 board/Marvell/octeon_ebb7304/MAINTAINERS create mode 100644 board/Marvell/octeon_ebb7304/Makefile create mode 100644 board/Marvell/octeon_ebb7304/board.c create mode 100644 configs/octeon_ebb7304_defconfig create mode 100644 include/configs/octeon_common.h create mode 100644 include/configs/octeon_ebb7304.h
