arm64: Add Juno board device tree.
Browse files Browse the repository at this point in the history 
This adds support for ARM's Juno development board (rev 0).
It enables most of the board peripherals: UART, I2C, USB, MMC and
100Mb ethernet. There is no support at the moment for clock setting
and HDLCD driver which depends on it.
