Kumar Gala ff4e66e93c pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarity 
The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.

Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

* File Name: 405gp_pci.c
*
* 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)
