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

Wed Jan 26 04:33:44 CET 2022
The GoFlex Home board has the network chip Marvell 88E1116R.
Use uclass mvgbe and the compatible driver M88E1118R 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 the network.
And remove ad-hoc code.
- Enable CONFIG_PHY_MARVELL to properly configure the network.
- Miscellaneous changes: use CONFIG_SYS_THUMB_BUILD to keep u-boot image
under 512K, use BIT macro, and cleanup comments.
