After a short test run, I decided to first ask for the boards before 
preparing a patch:

Boards in U-Boot but not in Linux (not updated):
- socfpga_cyclone5_dbm_soc1.dts
- socfpga_cyclone5_de0_nano_soc.dts (is this 
'socfpga_cyclone5_de0_sockit.dts'?)
- socfpga_cyclone5_de1_soc.dts
- socfpga_cyclone5_de10_nano.dts
- socfpga_cyclone5_is1.dts
- socfpga_cyclone5_sr1500.dts

Boards in Linux but not in U-Boot:
- socfpga_cyclone5_de0_sockit.dts (is this 
'socfpga_cyclone5_de0_nano_soc.dts'?)
- socfpga_cyclone5_sodia.dts

Also, Dinh has enabled the watchdog nearly 4 years ago in 
socfpga_cyclone5.dtsi but U-Boot doesn't. Should we keep it enabled or 
disable it in the U-Boot specific dts files?

Thanks,
Simon
