All I need for kernel debugging is BAT only translation. I cleared it
according to BDI2000 manual.

I looked at 2.4.14 kernel. It only has BDI2000 support in file
8260 uses different file. I searched that for traces of Abatron or BDI2000
without success.
I also downloaded ppc patch for 2.4.14. Same: no trace of "abatron" or
BDI2000 there.

Which lines do I have to add?
