Subject: [PATCH 10/18] PCI: dwc: designware: Provide page_size to pci_epc_mem
Date: Fri, 18 Aug 2017 20:28:02 +0530 [thread overview]
Message-ID: <20170818145810.17649-11-kishon@ti.com> (raw)
In-Reply-To: <20170818145810.17649-1-kishon@ti.com>
Use the newly introduced __pci_epc_mem_init instead of pci_epc_mem_init
to provide page_size to pci_epc_mem. This is in preparation for
adding EP support to K2G which has a restriction that the
address region should be either divided into 1MB/2MB/4MB or 8MB
sizes (Ref: 11.14.4.9.1 Outbound Address Translation in K2G TRM SPRUHY8F
January 2016 – Revised May 2017).
