Subject: [PATCH 10/12] MIPS: Get rid of BCM1250_M3_WAR
Date: Mon, 24 Aug 2020 18:32:52 +0200	[thread overview]
Message-ID: <20200824163257.44533-11-tsbogend@alpha.franken.de> (raw)
In-Reply-To: <20200824163257.44533-1-tsbogend@alpha.franken.de>

BCM1250_M3_WAR is depending on CONFIG_CONFIG_SB1_PASS_2_WORKAROUNDS.
So using this option directly lets and remove define.
