Subject: [RFC 8/8] ARM:stih41x: Add B2020 board support
From: Srinivas Kandagatla <srinivas.kandagatla@...com>
B2020 ADI board is reference board for STIH415/416 SOCs, it has 2 x
UART, 4x USB, 1 x Ethernet, 1 x SATA, 1 x PCIe, and 2GB RAM with
standard set-top box IPs.
This patch adds initial support to B2020 with STiH415/416 with SBC_UART1
as console and a heard beat LED.
