Re: [U-Boot] [PATCH v1 1/2] Revert "powerpc: mpc85xx: remove P2020DS board support"

Hi York,

This reverts commit 168dcc6cef7a0e13bc52fc8fa8de2866cf4033dc. Align with changes since P2020DS was removed, including adding these macros to defconfig

CONFIG_SYS_NS16550 CONFIG_CMD_NET CONFIG_NETDEVICES CONFIG_E1000 CONFIG_CMD_DHCP

Remove macros and include from board header file, including CONFIG_E1000 CONFIG_MTD_NAND_VERIFY_WRITE CONFIG_SYS_NS16550 config_cmd_default.h CONFIG_CMD_ELF CONFIG_CMD_SETEXPR CONFIG_CMD_NET

While we bring this board back, I believe we should add driver model support this this board as well, at least NS16550.

Fixed checkpatch errors of exceedding 80 characters, etc.

Changes in v1: Add back P2020DS, using generic board structure.
