Why do think you need the offset 0x2000? I just tested on my Sequoia under U-Boot and "see" the CPLD at address 0xc000.0000: => md.b c0000000 20 c0000000: 0f 00 c0 07 00 80 00 80 00 20 00 00 00 00 00 00 ......... ...... c0000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ So you should map not 0x1.c000.2000 but 0x1.c000.0000 under Linux. Please let me know if this works.
