From 645b302673bb74930b5f38f1d5b7e7532f164595 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 24 Apr 2022 14:36:35 +0200 Subject: ARM: pxa/sa1100: move I/O space to PCI_IOBASE PXA and StrongARM1100 traditionally map their I/O space 1:1 into virtual memory, using a per-bus io_offset that matches the base address of the ioremap mapping. In order for PXA to work in a multiplatform config, this needs to change so I/O space starts at PCI_IOBASE (0xfee00000). Since the pcmcia soc_common support is shared with StrongARM1100, both have to change at the same time. The affected machines are: - Anything with a PCMCIA slot now uses pci_remap_iospace, which is made available to PCMCIA configurations as well, rather than just PCI. The first PCMCIA slot now starts at port number 0x10000. - The Zeus and Viper platforms have PC/104-style ISA buses, which have a static mapping for both I/O and memory space at 0xf1000000, which can no longer work. It does not appear to have any in-tree users, so moving it to port number 0 makes them behave like a traditional PC. - SA1100 does support ISA slots in theory, but all machines that originally enabled this appear to have been removed from the tree ages ago, and the I/O space is never mapped anywhere. - The Nanoengine machine has support for PCI slots, but looks like this never included I/O space, the resources only define the location for memory and config space. With this, the definitions of __io() and IO_SPACE_LIMIT can be simplified, as the only remaining cases are the generic PCI_IOBASE and the custom inb()/outb() macros on RiscPC. S3C24xx still has a custom inb()/outb() in this here, but this is already removed in another branch.
