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 is v4 patchset support redundant boot on Rockchip 
rk3399.

Changes for v4:
- fixed compilation issue
- add wdt kconfig option
- tested wdt and bootcount
Changes for v3:
- rework of cru.h to include rk3288
- rebase on master
Changes for v2:
- Handle TPL build for watchdog, if TPL won't enable
- Fix comments for dw_wdt driver-model comments from Andy
- Add Kconfig items for WDT_TPL
- Support WDT on TPL as well
- Use SYS_SOC for cpu-info

Any inputs?
Jagan.
