Hello Guys,

I have been having a stab at compiling the kernel with those openWrt b53 
drivers , but not having much luck generating the kernel rpm . I have 
been following the fedora instructions from here :

https://fedoraproject.org/wiki/Building_a_custom_kernel

And have run into a few issues . Firstly it is the architecture , when 
executing this command :

rpmbuild -bb --target=`uname -m` kernel.spec

The target gets set to armv7l , this then unfortunately fails here :

+ InstallName=vmlinuz
+ Config=kernel-3.17.7-armv7l.config
+ DevelDir=/usr/src/kernels/3.17.7-300.R1.fc21.armv7l
+ '[' arch/arm/boot/zImage = vmlinux ']'
+ CopyKernel=cp
+ KernelVer=3.17.7-300.R1.fc21.armv7l
+ echo BUILDING A KERNEL FOR armv7l...
BUILDING A KERNEL FOR armv7l...
+ perl -p -i -e 's/^SUBLEVEL.*/SUBLEVEL = 7/' Makefile
+ perl -p -i -e 's/^EXTRAVERSION.*/EXTRAVERSION = -300.R1.fc21.armv7l/' Makefile
+ make -s mrproper
+ cp configs/kernel-3.17.7-armv7l.config .config
cp: cannot stat 'configs/kernel-3.17.7-armv7l.config': No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.awVfBd (%build)

because the file can not be found . The files in fact is called :

user@bananapi_r1 ~/rpmbuild/BUILD/kernel-3.17.fc21/linux-3.17.7-300.R1.fc21.armv7l/configs $ ls -l

Once I set the target manually to armv7hl , then the build process goes on further . But one thing that concerns me is that that I do  not see
any signs so far that my .config file is being used . The one that is copied is the generic one without the b53 driver being enabled . My
.config file is sitting in SOURCES due to this step in the instructions :

cp .config ~/rpmbuild/SOURCES/config-`uname -m`-generic

And it is here amongst other generic .config's :

-rw-r--r-- 1 msou msou     5912 Dec 17 13:52 config-arm-generic
-rw-r--r-- 1 msou msou    14897 Dec 17 13:52 config-armv7
-rw-r--r-- 1 msou msou    20997 Dec 17 13:52 config-armv7-generic
-rw-rw-r-- 1 msou msou   157215 Jan  6 00:33 config-armv7l-generic
-rw-r--r-- 1 msou msou     2169 Dec 17 13:52 config-armv7-lpae

The one I created is config-armv7l-generic , while the others are called just armv7 with no 'l' . So far we have 3 different ways to
designate the platform : armv7 , armv7l and armv7hl and I am not sure which one to use and where .

My work flow for this tends to be roughly:
"fedpkg clone kernel"
add patches and update kernel.spec
"fedpkg prep" which will locally make sure all the patches apply cleanly etc
"fedpkg srpm"
"rpmbuild --rebuild --target armv7hl --with=cross --without=perf
--without=debuginfo --without=pae --define="_arch arm"
--define="_build_arch arm" --define="__strip
/usr/bin/arm-linux-gnu-strip" kernel.src.rpm"
