From 7c2584faa145991558412d135d9e1d3431f47c6d Mon Sep 17 00:00:00 2001 From: Sergio Paracuellos Date: Sat, 25 Sep 2021 22:32:22 +0200 Subject: [PATCH] PCI: Allow architecture-specific pci_remap_iospace() pci_remap_iospace() was originally meant as an architecture specific helper but it moved into generic code after all architectures had the same requirements. MIPS has different requirements so it should not be shared. The way for doing this will be using a macro 'pci_remap_iospace' defined for those architectures that need a special treatment. Hence, put core API function inside preprocesor conditional code for 'pci_remap_iospace' definition.
