Subject: [PATCH 2/4] MIPS: cmdline: Remove CONFIG_MIPS_CMDLINE_DTB_EXTEND
Date: Mon, 7 Oct 2019 22:20:02 +0000	[thread overview]
Message-ID: <20191007221951.1889661-2-paul.burton@mips.com> (raw)
In-Reply-To: <20191007221951.1889661-1-paul.burton@mips.com>

CONFIG_MIPS_CMDLINE_DTB_EXTEND is not selected by any of our defconfigs,
so remove it to simplify the messy command line logic in arch_mem_init()
a little.
