- Add DM based generic watchdog start and reset implementation
  and remove all ad-hoc implementations (Stefan)
- Move mv_sdhci to DM (Pierre)
- Misc turris_omnia updates (Pierre)
- Change openrd targets to correctly build again (size changes
  and fixes to the dts targets) and bring it back into Travis
  builds (Stefan)
- Add Kirkwood db-88f6281-bp board (Chris)

+Important! Changes since v2019.07
+---------------------------------
+In u-boot v2019.07 the driver for the SATA port was changed to a new
+one. This means that the old "ide" command and block interface is not
+supported anymore. More important, the boot commands have changed. You have
+to overwrite the boot commands in your envionment with the new ones:
+
+  env default -f bootcmd_legacy
+  env default -f bootcmd_hdd
