- * Compiling the following simply requires the presence of <linux/pci.c>.
- * Actually running this is another matter altogether...
- *
- * This scheme requires that the kernel allow mmap()'ing of a host bridge's I/O
- * and memory spaces through its /proc/bus/pci/BUS/DFN entry.  Which one is
- * determined by a prior ioctl().
- *
- * For the sparc64 port, this means 2.4.12 or later.  For ppc, this
- * functionality is almost, but not quite there yet.  Alpha and other kernel
- * ports to multi-domain architectures still need to implement this.
- *
- * This scheme is also predicated on the use of an IOADDRESS compatible type to
- * designate I/O addresses.  Although IOADDRESS is defined as an unsigned
- * integral type, it is actually the virtual address of, i.e. a pointer to, the
- * I/O port to access.  And so, the inX/outX macros in "compiler.h" need to be
- * #define'd appropriately (as is done on SPARC's).
- *
- * Another requirement to port this scheme to another multi-domain architecture
- * is to add the appropriate entries in the pciControllerSizes array below.
- *
- * TO DO:  Address the deleterious reaction some host bridges have to master
- *         aborts.  This is already done for secondary PCI buses, but not yet
- *         for accesses to primary buses (except for the SPARC port, where
- *         master aborts are avoided during PCI scans).
