Ok, then this should probably go into a x3455 board specific code
instead. I saw Yinghai made a lot of io to those ports in the ht1000
specific code, so I assumed thats southbridge specific code.

The weird thing is that I could overwrite some parts of the flash
without that code (0x70000 to 0x80000), so it's probably not the flash
write line.

Or, it might be the FPGA on board catches the area from 0x70000 to
0x80000 and decides whether to switch or not. I have no information on
that, unfortunately, and I doubt I will be able to get it in a timely

I will prepare something to make this board dependent. Thank you very
much for the feedback.
