Info on AT91 patches against mainline kernel

Info on AT91 patches against mainline kernel

[Ravi Kumar Kulkarni]

Hi all,
I want some info on the status of AT91 Patches against the mailine 
kernel tree.I'm having a AT91 SOC board AT91SAM9261. The Note on their 
website (wwwdotlinux4samdotorg)says to get a kernel up on the board we 
have to apply the AT91 patch set maintained by Andrew Victor which is 
located at (http://maxim.org.za/at91_26.html) . There are only patches 
upto 2.6.31. so does tat mean i cannot compile the latest mainline 
kernel (2.6.33) for my board and use some new features. or i have to 
wait till andrew updates them to mainline? can some body please clarify 
me this? Also since 2.6.32 would have a longer maintainance cycle 
wouldnt it be nice if we have 2.6.32 at91 patch so tat we can use this 
in production systems. please CC me when u reply since im not subscibed 
to list .thanks
warm regards,
Ravi Kulkarni

You do not necessarily need the at91-patchset from Andrew.
2.6.33 works fine on at91sam9261 without it...

Thanks for the info. I will try to compile 2.6.33  now. But i got a mail 
from andrew  that he updated at91 patchset to 2.6.32 . for clarification 
jus verifying tat u mean  from 2.6.33 onwards  u  don't need at91 
patches and can directly compile without waiting Andrew's patchset . If 
tats case then Andrew can update that in linux4samdotorg website so that 
it will be helpful for all of us.thanks.

You only need the changes from Andrew in case there is something in
there that you require, you should look at the changelog to be sure.
But, the at91sam9261 is already for several years in mainline and it
works fine (even much older kernels than 2.6.33 will work without it,
for example we used 2.6.24, 2.6.26, 2.6.31 without it), Andrews
patchset is just a set of additional changes that will likely be
pushed to mainline at some time.
