From 95ff7c955376d5bd52f044f445ea04eab4fb0f9a Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Thu, 2 Jul 2009 23:19:33 +0800 Subject: [PATCH] MIPS: Loongson: Remove out-of-date board-specific kgdb source code Since the re-implementation of kgdb by commit 8854700115ecf8aa6f087aa915b7b6cf18090d39 the platform-specific version has become superfluous, remove it.
