Mon Apr 18 01:42:32 CEST 2022
The Globalscale Technologies Sheevaplug board has the network chip
Marvell 88E1116R. Use uclass mvgbe and the compatible driver M88E1310
driver to bring up Ethernet.
- Remove CONFIG_RESET_PHY_R symbol from all board files
- Use uclass mvgbe to bring up the network. And remove ad-hoc code.
- Enable CONFIG_PHY_MARVELL to properly configure the network.
- Miscellaneous changes: Move constants to .c file and remove header file
board/Marvell/sheevaplug/sheevaplug.h, use BIT macro, and add/cleanup
comments.

Changes in v2:
- Remove CONFIG_RESET_PHY_R from configs file and it is no longer needed
to undefine it in include board file.
- Misceslanous changes: enable CONFIG_SYS_64BIT_LBA (for large HDD & USB),
CONFIG_CMD_FS_GENERIC (generic load cmd), CONFIG_CMD_SETEXPR (enhance
shell expression).
