[PATCH] arm: kirkwood: Pogoplug E02 : Convert Ethernet to Driver Model

Wed Feb 9 03:56:22 CET 2022
The Pogoplug E02 board has the network chip Marvell 88E1116R. Convert
to Driver Model and use uclass mvgbe and the compatible driver M88E1118R
to bring up Ethernet.
- Add board_eth_init(), CONFIG_DM_ETH, and CONFIG_PHY_MARVELL
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.
- As the result of the migration to Driver Model, this u-boot image has
grown substantially (about 100K, give or take). The old envs location
at 0x60000 (384k) is no longer possible. Move it to 0xC0000 (768K).
- Miscellaneous changes: Move constants to .c file and remove header file
board/cloudengines/pogo_e02/pogo_e02.h, use CONFIG_SYS_THUMB_BUILD to
keep u-boot image under 512K, use BIT macro, and cleanup comments.
