From e60865572f81fb2687163fd37ea37cd4283e0bce Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 26 Mar 2014 21:40:25 +0100 Subject: [PATCH] MIPS: Fix build error due to multiple prom_putchar() definitions. This can happen if both the generic 8250 and another early console driver are enable. Fixed by using an auxilliary kconfig symbol to restrict that choice.
