Subject: Re: [PATCHv2 2/2] PCI: layerscape: EP and RC drivers are compiled separately
Date: Wed, 26 Jun 2019 12:51:53 -0500 [thread overview]
Message-ID: <20190626175153.GC103694@google.com> (raw)
In-Reply-To: <20190626111139.32878-2-xiaowei.bao@nxp.com>
If you post another revision for any reason, please change the subject
so it's worded as a command and mentions the new config options, e.g.,
PCI: layerscape: Add CONFIG_PCI_LAYERSCAPE_EP to build EP/RC separately
