tah reset?

My intention is not to waste anybody's time and I think, I did not. As I mentioned to you earlier that I am working on the vendor provided version of Linux Kernel 2.4.27-pre3, which looks clearly from kernel.org. The value of PPC440GX_TAH0_ADDR and PPC440GX_TAH1_ADDR in arch/ppc/platforms/ibm440gx.h is 0x0000000140000b00 & 0x0000000140000d00 respectively. I verified this value in lk 2.4.30 also, these values are the same.

Though in lk 2.6.x, the values have been hardcoded in the arch/ppc/platforms/ibm440gx.c to 0x0000000140000b50 and 0x0000000140000d50. Therefore, the confusion.

I hope this clears your misunderstanding. I did not see your suggestion for using your version of 2.4.x backported driver of ibm_emac. I could use it, if you send it again.

Thanks,
Sanjay

Linux 2.6 has correct values for TAH base address, 2.4 doesn't have 
any support for TAH at all.

Where did you get this incorrect code?

You see, you should have used supported sources (2.6) or the one I 
recommended to you (my 2.4 backport) but you have ignored this  
suggestion and wasted your time and time of people on this mail list.

Please, next time if you use some stuff which isn't in kernel.org's 
tree, direct you questions to the person who made those patches, 
because we cannot help you as we don't have the source code you are 
using.
