- * Modified for MIPS by Jun Sun, jsun@mvista.com
- *
- * . Simplify the interface between pci_auto and the rest: a single function.
- * . Assign resources from low address to upper address.
- * . change most int to u32.
- *
- * Further modified to include it as mips generic code, ppopov@mvista.com.
- *
- * 2001-10-26  Bradley D. LaRonde <brad@ltc.com>
- * - Add a top_bus argument to the "early config" functions so that
- *   they can set a fake parent bus pointer to convince the underlying
- *   pci ops to use type 1 configuration for sub busses.
- * - Set bridge base and limit registers correctly.
- * - Align io and memory base properly before and after bridge setup.
- * - Don't fall through to pci_setup_bars for bridge.
- * - Reformat the debug output to look more like lspci's output.
- *
- * Cloned for SuperH by M. R. Brown, mrbrown@0xd6.org
- *
- * 2003-08-05  Paul Mundt <lethal@linux-sh.org>
- * - Don't update the BAR values on systems that already have valid addresses
- *   and don't want these updated for whatever reason, by way of a new config
- *   option check. However, we still read in the old BAR values so that they
- *   can still be reported through the debug output.
