Evaluation Board User?s Manual) has mentioned about the PCI memory as: Start Address (32 Bit) - 9000 0000 End Address (32 Bit) - 9FFF FFFF Start Address (36 Bit) - 3 0000 0000 End Address (36 Bit) - 3 0FFF FFFF Size - 256MB 256 MB I am not clear about the logic behind the value assigned to CFG_PCI_MEMBASE i.e. 0x80000000 Can you help me to figure it out?
