Forgot to mention that following has been tested with this series:
- Loading TPL/SPL and FIT from a combo of different sources, e.g. SPL in
  eMMC and FIT in SD-card or SPL in SD-card and FIT in eMMC etc.
- USB host e.g. usb start; usb tree; usb stop;
- Ethernet e.g. mdio list; mii info; net list; dhcp;
- No pinctrl issue is reported with CONFIG_LOGLEVEL=7, i.e. no print of
  "pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19"
- GPIO and regulator status using gpio status; regulator status;
- Manually inspect TPL and SPL device tree
  $ dtc -I dtb -O dts tpl/u-boot-tpl.dtb
  $ dtc -I dtb -O dts spl/u-boot-spl.dtb

On the following devices:
- Rock64 v2.0 and v3.0
- ROC-RK3328-CC v1.0 and v1.3
- ROCK Pi E v1.21
- Orange Pi R1 Plus LTS

Following devices have _not_ been tested:
- NanoPi R2C/R2C Plus/R2S
- Orange Pi R1 Plus

A USB host issue was discovered on Orange Pi R1 Plus LTS during testing
and I expect NanoPi R2* boards also have the same issue. A fix for this
will be sent separately. The issue relates to fdt address translation of
reg prop in usbdrd3 node.

Jonas
