Subject: [PATCH 00/15] rk3399: Add redundant boot support
Date: Mon, 29 Jul 2019 13:16:56 +0530	[thread overview]
Message-ID: <20190729074711.16988-1-jagan@amarulasolutions.com> (raw)

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.

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.
