Using Xilinx Framebuffer on ML405 and 2.6.20.4

Using Xilinx Framebuffer on ML405 and 2.6.20.4

[Peter Mendham]

Dear all,

I am wanting to use the Xilinx TFT controller from the ML403/5 reference 
project (probably from ML300 as well) under a 2.6.20.4 kernel.  I have 
Grant Likely's patchset applied in which there is a platform device 
entry for the framebuffer.  Does anyone know if there is mainline 
support for the Xilinx-style framebuffer?  If so, how do I enable it?  I 
have included framebuffer support in my kernel build, but I assume I 
need a driver also? Any tips greatly appreciated.

Thanks in advance,
-- Peter

Heh, I've got a driver.  I just haven't published it yet.  Give me a few days...

Fantastic.  I'm happy to be on the front line of alpha testing if that's 
any help.

No worries with a few day's delay though, I'm trying to fit the TFT 
controller into with my design with a TEMAC in it and I'm having some 
serious issues meeting timing requirements.  The SystemACE controller 
just gives up the ghost loading the kernel image.  If you or anyone else 
has any tips on how to get designs that fail timing to work I'd love to 
hear them.  The other thing is a sanity check: I've assumed the reason 
the SystemACE controller is giving up is a bus mess-up caused by 
timing.  Any better ideas?

Do you have a patch that I can apply to a mainline kernel to include the 
driver?

Thanks,

To be continued: we have one too :)
I guess fb support is too simple, as too many people have wrote that driver
...
