From 222b27713d7f7e189cca30ccdcee8e1f953d2c9f Mon Sep 17 00:00:00 2001 From: Sergio Paracuellos Date: Mon, 14 Jun 2021 12:06:15 +0200 Subject: [PATCH] MIPS: ralink: Define PCI_IOBASE PCI_IOBASE is used to create VM maps for PCI I/O ports, it is required by generic PCI drivers to make memory mapped I/O range work. Hence define it for ralink architectures to be able to avoid parsing manually IO ranges in PCI generic driver code. Function 'plat_mem_setup' for ralink is using 'set_io_port_base' call using '0xa0000000' as address, so use the same address in the definition to align things.
