Subject: [PATCH 01/19] PCI: keystone: Use quirk to limit MRRS for K2G
Date: Mon, 15 Oct 2018 18:37:03 +0530 [thread overview]
Message-ID: <20181015130721.5535-2-kishon@ti.com> (raw)
In-Reply-To: <20181015130721.5535-1-kishon@ti.com>
PCI controller in K2G also has a limitation that memory read request
size (MRRS) must not exceed 256 bytes. Use the quirk to limit MRRS
(added for K2HK, K2L and K2E) for K2G as well.
