Subject: [U-Boot-Users] [PATCH][MIPS] cpu/mips/cache.S: Add dcache_enable
Date: Fri, 02 May 2008 12:35:50 +0900	[thread overview]
Message-ID: <481A8C16.7090502@ruby.dti.ne.jp> (raw)
In-Reply-To: <481A8B97.5030209@ruby.dti.ne.jp>

Recent bootelf command fixes (017e9b7925f74878d0e9475388cca9bda5ef9482,
