B2000 board is reference board for STIH415/416 SOCs, it has
2 x UART, 4x USB, 2 x Ethernet, 1 x SATA, 1 x PCIe, and 1GB RAM.
This patch add initial support to b2000 with STiH415/416 with UART2 as
console and a heard beat LED.

I probably wouldn't bother listing all the boards here. Just make sure
the .dts file lists both the name of the board and of the soc in
