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. Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: Bert Vermeulen <redacted>
