| * 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) |
