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
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

both Octeon base support series are applied to u-boot-mips/next. I reordered and squashed some patches to get a cleaner history. Also configs/octeon_ebb7304_defconfig needed a little refresh. The GPIO driver needs another update and the SPI driver some more review and ack. For the DDR4 init stuff I couldn't spare enough time for review yet.
Could you check if everything still works so that I can prepare the pull-request? Thanks.
