Re: [microblaze-uclinux] bridge-utils conversion to flat binary

[Paul Hartke <phartke@xxxxxxxxxxxx>]

Thanks--the program is executing now.

However, my "friend" couldn't figure out how to apply the patch so he did it
manually but looking at the file.  For future reference, how should he have
done it using the patch command?

I hope this patch can be submitted to the mainline uclinux repository. 
However, I still don't see the GPIO update at
http://cvs.uclinux.org/cgi-bin/cvsweb.cgi/uClinux-dist/vendors/Xilinx/uclinux-auto/Makefile?rev=1.1.1.4;content-type=text%2Fplain
Do you know the schedule for the next uClinux-dist release(s)?
