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.
Yes, since today is the day we are supposed to have all serial drivers converted over.
Other things that could perhaps be converted, and would give PPC a better start on driver model: i2c, mmc, usb, Ethernet, PCI :-)
I will take this chance to convert P2020DS to use DM. Need some guidance here. For NS16550, it needs the clock. To keep it simple, let's presume platform data is used. My trouble is the clock is not unknown at compiling time. It needs to be updated by checking the board/soc configuration after power up. The clock is only available after get_clocks() is called in init_sequance. Is there a way I can update the clocks before the driver is initialized?

See this commit:
858530a8 dm: tegra: Enable driver model for serial
It sets up its own clock.
