From 05e342554e51767830d7e60f2dab09192fd2a0e1 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 29 Jan 2016 13:54:52 +0000 Subject: MIPS: Support dynamic I/O port base address The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta.
