Boot redundancy is one of the key criteria for switch recovery or golden partition based on the bootcount value, which indeed very much needed in production systems on the fields.
This patchset support redundant boot on Rockchip rk3399.
Thanks for your patches, you will need to update your patches upon
latest mainline U-Boot.
Thanks,

To make full functional redundancy below features would require from U-Boot level.
- bootcount, for counting number reboots
- altboot
- watchdog support, if SPL or U-Boot reset because of WDT
- add CPUINFO for more understanding about how SoC and reset reason.
patch 0001 - 0005: cpu info, reset reason
patch 0006 - 0009: designware watchdog driver, dm-conversion
patch 0010: Add watchdog property available to SPL
patch 0011: Add Kconfig option for dw_wdt.c
patch 0012: Disable watchdog for TPL
patch 0013: enable watchdog on rockpro64, overlay
patch 0014: bootcount support
patch 0015: enable bootcount on rockpro64, overlay
I would like, not to merge watchdog and bootcount on Mainline devboards since these features will mostly required on production devices but any comments, please share.
Any inputs? Jagan.
