From c3d8d85019c9e4f6e4f23d194b6432a2c2464372 Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Sat, 28 Nov 2009 14:21:50 +0800 Subject: MIPS: Loongson: Cleanups of serial port support This patchs uses a loongson_uart_base variable instead of the uart_base[] array and adds a new kernel option to avoid to compile uart_base.c all the time, which will save a little bit of memory for us.
