Sun Apr 17 22:42:42 CEST 2022
The Zyxel NSA310s board has the network chip Marvell Alaska 88E1318S.
Use uclass mvgbe and the compatible driver M88E1310 driver to bring
up Ethernet.
- Use uclass mvgbe to bring up the network. And remove ad-hoc code.
- Remove CONFIG_RESET_PHY_R.
- Enable CONFIG_PHY_MARVELL to properly configure the network.
- Add phy mode RGMII to kirkwood-nsa310s.dts
- Miscellaneous changes: Move constants to .c file and remove header file
board/zyxel/nsa310s/nsa310s.h, add support for large USB and SATA HDDs,
use BIT macro, add/cleanup comments, and cosmetic changes.
Note that this patch is depended on the following patch:
