+Subject: [PATCH 01/90] PCI: mvebu: Replace pci_ioremap_io() usage by
+ devm_pci_remap_iospace()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Now when ARM architecture code also provides standard PCI core function
+pci_remap_iospace(), use its devm_pci_remap_iospace() variant in
+pci-mvebu.c driver instead of old ARM-specific pci_ioremap_io() function.
+
+Call devm_pci_remap_iospace() before adding IO resource to host bridge
+structure, at the place where it should be.
+
