Some questions about the Xilinx Temac driver.

[Ming Liu]

Dear Chris,
Thanks for your telling. I have seen that guidance. But I think that is 
specific for the MontaVista linux. In that guidance, it just says to copy 
the generated directories and files into the kernel tree and then configure 
and make zImage. However it doesn't work for my 2.6.16 kernel. 

Any other idea on how to implement such an EDK-generated BSP in the kernel 
like mine? Thanks for any suggestion.

BR
Ming

><----> Dear Michael,
><----> Now I update my Xilinx design software from 8.1 to 8.2 and notice
><----> that
><----> there is already linux_2_6 support. Then I generated the BSP for
><----> linux 2.6.
><----> I found that there are some differences from the older version, 
e.g.
><----> there
><----> are some files such as XMakefile, xps_connected.cud, etc. I am
><----> confused
><----> with this. So could you please give me a hand on how to use such a
><----> generated BSP to build my linux 2.6 kernel? I cannot find any
><----> guidance on
><----> how to do that. Thanks for your help.
