Subject: [PATCH v2 02/12] mips: start.S: Don't call mips_cache_reset() on ARCH_OCTEON
Date: Thu, 14 May 2020 11:59:02 +0200 [thread overview]
Message-ID: <20200514095912.14428-3-sr@denx.de> (raw)
In-Reply-To: <20200514095912.14428-1-sr@denx.de>
Since Octeon now runs from L2 cache, we can't reset the cache at this
time. So let's opt-out this function on Octeon, as the cache is
coherent on Octeon anyways.
