Was already able to find the firmware since it was included with the installation 
of the fedora 20 on the notebook. Issue is that I placed the firmware files into the
 /lib/firmware directory, but on booting from my project kernel it seems to try and 
load firmware during the kernel loading before the ramdisk.lzma is loaded. The 
kernel is built with the option to not include firmware, since I don't know what if 
any firmware will be needed by end users.  This seems to have worked with 
bnx2  and bnx2x firmware that another end user needed. 

But the booting showed the messages before the ramdisk.lzma is 
recognized, and then shows messages with =-12, and =-2. Didn't save the 
output since this was a ram only load. Was thinking that mdev -s might cause 
it to load firmware. Kernel contains most disk and ethernet devices included.
