Hi Daniel,

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.
Thanks Daniel. I checked the "next" branch and all looks good. Running this on the board also works without any issues. The only thing I noticed is, that building U-Boot now produces this build warning:
===================== WARNING ====================== This board does not use CONFIG_DM_ETH (Driver Model for Ethernet drivers). Please update the board to use CONFIG_DM_ETH before the v2020.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/migration.rst for more info. ====================================================
Feel free to add (squash) this change to the defconfig to remove this build warning:
diff --git a/configs/octeon_ebb7304_defconfig b/configs/octeon_ebb7304_defconfig index d810b1e45f..204a42b9fd 100644 --- a/configs/octeon_ebb7304_defconfig +++ b/configs/octeon_ebb7304_defconfig @@ -29,6 +29,7 @@ CONFIG_CFI_FLASH=y CONFIG_SYS_FLASH_USE_BUFFER_WRITE=y CONFIG_FLASH_CFI_MTD=y CONFIG_SYS_FLASH_CFI=y +CONFIG_DM_ETH=y # CONFIG_NETDEVICES is not set CONFIG_DEBUG_UART_SHIFT=3 CONFIG_DEBUG_UART_ANNOUNCE=y
Or I will send a patch to change it when the patch series is merged into mainline.
Thanks, Stefan
