Add libfdt support to qemu

This patch libfdt support into the qemu configuation script. There is a portion 
for libfdt probing that is has some XXX. The code commented out is how to 
properly do probing for a library, the issue is that with kvm-userspace we do 
not build libfdt before configuring qemu. So to pervent this check from failing 
everytime we just do a simple test with the libfdt header. Once this can be 
resolved elgantly then we can uncomment the place commented out and remove the 
lines below them.

Re: [kvm-devel] [PATCH 2 of 7] Add libfdt support to qemu

2008-03-15 Thread Anthony Liguori

Instead of having an explicit --enable-libfdt, it would be nicer to 
compile probe for it and then provide a --disable-libfdt option.  Then 
it Just Works without a special configure flag.

Regards,

Anthony Liguori
