From fc2ca674470bbfe11d72a20a3f19fd3dc43bfca0 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 30 Aug 2015 21:19:58 -0700 Subject: MIPS: Fix console output for Fulong2e system Commit 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface") made the number of UARTs dynamic if LEFI_FIRMWARE_INTERFACE is configured. Unfortunately, it did not initialize the number of UARTs if LEFI_FIRMWARE_INTERFACE is not configured. As a result, the Fulong2e system has no console.
