From: John Crispin <john@phrozen.org> Add basic support for EcoNet EN7523, enough for booting to console. The UART is basically 8250-compatible, except for the clock selection. A clock-frequency value is synthesized to get this to run at 115200 bps.

Looking at this again, I was under the impression that Cortex-A7 only supported GICv2; is this actually a Cortex-A7 or a different CPU? Which revision is this?
