Subject: [PATCH 4/9] powerpc/64s: dt_cpu_ftrs fix POWER9 DD2.2 and above
Date: Wed, 21 Feb 2018 05:08:27 +1000 [thread overview]
Message-ID: <20180220190832.1872-5-npiggin@gmail.com> (raw)
In-Reply-To: <20180220190832.1872-1-npiggin@gmail.com>
The CPU_FTR_POWER9_DD2_1 flag is intended to be set for DD2.1 and
above (which is what the cputable setup does). Fix dt_cpu_ftrs setup
to match.
