- * Function: Initialization code for the 405GP PCI Configuration regs.
- *
- * Author: Mark Game
- *
- * Change Activity-
- *
- * Date Description of Change BY
- * --------- --------------------- ---
- * 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)

- *
- * Enpoint cofiguration can be verified by connecting Yucca board to any

+ * Function: Initialization code for the 405GP PCI Configuration regs.
+ *
+ * Author: Mark Game
+ *
+ * Change Activity-
+ *
+ * Date Description of Change BY
+ * --------- --------------------- ---
+ * 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)
