 *  ---------   ---------------------                                       ---
 *  09-Sep-98   Created                                                     MCG
 *  02-Nov-98   Removed External arbiter selected message                   JWB
 *  27-Nov-98   Zero out PTMBAR2 and disable in PTM2MS                      JWB
 *  04-Jan-99   Zero out other unused PMM and PTM regs. Change bus scan     MCG
 *              from (0 to n) to (1 to n).
 *  17-May-99   Port to Walnut                                              JWB
 *  17-Jun-99   Updated for VGA support                                     JWB
 *  21-Jun-99   Updated to allow SRAM region to be a target from PCI bus    JWB
 *  19-Jul-99   Updated for 405GP pass 1 errata #26 (Low PCI subsequent     MCG
 *              target latency timer values are not supported).
 *              Should be fixed in pass 2.
 *  09-Sep-99   Removed use of PTM2 since the SRAM region no longer needs   JWB
 *              to be a PCI target. Zero out PTMBAR2 and disable in PTM2MS.
 *  10-Dec-99   Updated PCI_Write_CFG_Reg for pass2 errata #6               JWB
 *  11-Jan-00   Ensure PMMxMAs disabled before setting PMMxLAs. This is not
 *              really required after a reset since PMMxMAs are already
 * 	        disabled but is a good practice nonetheless.                JWB
 *  12-Jun-01   stefan.roese@esd-electronics.com
 *              - PCI host/adapter handling reworked
 *  09-Jul-01   stefan.roese@esd-electronics.com
 *              - PCI host now configures from device 0 (not 1) to max_dev,
 *                (host configures itself)
 *              - On CPCI-405 pci base address and size is generated from
 *                SDRAM and FLASH size (CFG regs not used anymore)
 *              - Some minor changes for CPCI-405-A (adapter version)
 *  14-Sep-01   stefan.roese@esd-electronics.com
 *              - CONFIG_PCI_SCAN_SHOW added to print pci devices upon startup
 *  28-Sep-01   stefan.roese@esd-electronics.com
 *              - Changed pci master configuration for linux compatibility
 *                (no need for bios_fixup() anymore)
 *  26-Feb-02   stefan.roese@esd-electronics.com
 *              - Bug fixed in pci configuration (Andrew May)
 *              - Removed pci class code init for CPCI405 board
 *  15-May-02   stefan.roese@esd-electronics.com
 *              - New vga device handling
 *  29-May-02   stefan.roese@esd-electronics.com
 *              - PCI class code init added (if defined)
