The doc most probably only refers to the virtual address mapped in U-Boot 
here.

Hi Stefan,

I finally got the new pdf files from other Resource CDs and used 0xc00 
address, without 0x2000 offset.

It works! Thanks a lot for the help.

But may I know why in Linux it is mapped to 0x1c00, wherein the doc stated 
0xc00?

Thanks a lot!

Please refer to the document describing the CPLD registers. They are byte 
registers and not 32bit lword registers (see below).

The address of the CPLD is without this 0x2000 offset as it seems. Maybe the 
Sequoia users manual is incorrect here.

Make sure that you address these registers with the correct functions. That is 
in_8()/out_8(). Here a log from U-Boot:

=> md.l c000 1
c000: 0f00c007
=> md.b c000 4
c000: 0f 00 c0 07

By writing 0x00 to offset 0x02 (LED control) I am able to set the user led's. 
This should work in Linux the same way:

=> mw.b c002 00

Stefan

Why do think you need the offset 0x2000? I just tested on my Sequoia under 
U-Boot and "see" the CPLD at address 0xc000.:

=> md.b c000 20
c000: 0f 00 c0 07 00 80 00 80 00 20 00 00 00 00 00 00. ..
c010: 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. under Linux. Please let 
me know if this works.

Stefan

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

This is board specific information and not CPU specific. The CPLD with it's 
BCSR is a Sequoia thing and can therefor not be listed in the 440EPx manuals. 
It it located on the EBC though which is documented in the 440EPx manuals.

So if this chips select which is connected to the CPLD is mapped to 
0xc000. which is the case for Sequoia, then you will "find" these 
registers at physical address 0x1.c000.. And should use ioremap64() to 
get the virtual address to access this CPLD.

Please take a look at the 440EPx data sheet. It has a nice table with an 
overview of the address maps (table 1). Here you will notice that the EBC has 
multiple maps, one starting at 0x1.c000. and another one at 
0x1.f000.. Yes, these are 36bit physical addresses. In U-Boot these are 
mapped via the TLB to 0xc000. and 0xf000.. So in U-Boot you are able 
to access the CPLD at 0xc000. But in Linux you have to map the 36bit 
address to get the virtual address which you need for accessing. And using 
arch/ppc you need to call ioremap64() with this 36bit address as parameter.

Hope this helps.
