[PATCH v3] arm: kirkwood: nas220: Add DM Ethernet, SATA, GPIO

Hajo Noerenberg hajo-uboot at noerenberg.de
Wed Mar 9 10:27:34 CET 2022 

Bring the NAS220 board up to current standards. This is basically an adaptation of the changes Tony Dinh implemented for the Dockstar board.

- Implement the changes to v2 as suggested by Stefan Roese
- Add CONFIG_SUPPORT_PASSING_ATAGS et al, otherwise standard Debian flash-kernel pkg is unable to start kernel
- Add CONFIG_SYS_64BIT_LBA, basic read tests with a 4TB hdd succeed with my NAS220 hardware

- Thanks to Stefan and Tony
