[PATCH] arm: kirkwood: Dreamplug : Use Marvell uclass mvgbe and PHY driver for Ethernet

Tony Dinh mibodhi at gmail.com
Mon Jan 31 00:02:30 CET 2022


The Globalscale Technologies Dreamplug board has the network chip
Marvell 88E1116R. Use uclass mvgbe and the compatible driver M88E1310
driver to bring up Ethernet.

- Currently, CONFIG_RESET_PHY_R symbol is used in
arch/arm/mach-kirkwood/include/mach/config.h for all Kirkwood
boards with mv8831116 PHY, with each board defines the function
reset_phy(). Undefine it for this board.
- Add board_eth_init() to use uclass mvgbe to bring up both network
port 0 and 1. And remove ad-hoc code.
- Enable CONFIG_PHY_MARVELL to properly configure the network.
- Add myself as maintainer (this board seems to be orphaned,
could not contact Jason Cooper using current email).
- Miscellaneous changes: Move constants to .c file and remove header file
board/Marvell/dreamplug/dreamplug.h, cleanup comments.
