Subject: [PATCH 2/4] MIPS: Remove unused R5432 CPU support
Date: Mon, 22 Jul 2019 21:59:50 +0000	[thread overview]
Message-ID: <20190722215705.20109-2-paul.burton@mips.com> (raw)
In-Reply-To: <20190722215705.20109-1-paul.burton@mips.com>

Our R5432 CPU support can only be included if a system selects
CONFIG_SYS_HAS_CPU_R5432. No system does, making all R5432-related CPU
support dead code. Remove it.
