I see. No wonder I couldn't get more information on BCSR. I should contact
sequoia to get the proper details like the correct addresses.

I already used ioremap64(), remapping 0x1c0002000. I got a hex value for
the Board ID but could figure out what it means. So I tried the
USER_LED0/USER_LED1 (base address+0x2), to see if I could turn on/off the
user LEDS, but still no luck. I think I am accessing the wrong addresses so
I need to verify it with them.

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.

Best regards,
