* - pci_space0_addr: configurable
* - pci_space1_addr configurable
*
* Local Map:
* ----------
* Local addresses (Remap)
* - SDRAM 0x06000000 Size 16MByte mask 0xff000000
* - EPLD CFG 0x07000000 Size 512Bytes
* - FLASH 0x03000000 Size up to 8MByte
* - CPU 0x01000000 Size 4MByte (only accessable if special configured)
*
* Implemention:
* -------------
* To prevent using large resources reservation on the host following
* PCI mapping is choosed:
* - pci_cfg_mem_base: fixed address to the PLX config area size 512Bytes
* - pci_space0_addr: configured to the EPLD Config Area size 256Bytes
* - pci_space1_addr: configured to the SDRAM Area size 1MBytes, this
* space is used to switch between SDRAM, Flash and CPU
