+config BR2_PACKAGE_OCF
+	bool "ocf"
+	help
+	  OCF-Linux is a Linux port of the OpenBSD/FreeBSD Cryptographic
+	  Framework (OCF). This port aims to bring full asynchronous HW/SW
+	  crypto acceleration to the Linux kernel and applications
+	  running under Linux.
+	  
+	  http://ocf-linux.sourceforge.net/
+
+config BR2_PACKAGE_OPENSSL_OCF
+	bool "openssl ocf support"
+	depends on BR2_PACKAGE_OPENSSL
+	help
+	  Enable openssl cryptodev (OCF) hardware acceleration support.
+	  This requires kernel patches from the ocf-linux project otherwise
+	  you'll just have a bigger openssl library that works as usual.

Copy/Paste too much from your example maybe?

 I guess this is an attempt to keep the options alphabetical...  but 
they're not :-)  I'd put OCF at the top or at the bottom.  The top
is closest to alphabetical.

 I'm not sure if 'cp -rf' is the best option here...  First of all, '-a'
seems better in order to keep symlinks.  Second, the '-f' removes the 
files before they're overwritten, which is kind of pointless I think --
if they need to be removed, do an 'rm -rf' first.  Instead of cpio I'd
use the tar-path (cfr. Peter's correction to the linux-firmware 
package) (actually, I'd have used cpio rather than tar because it's a 
bit simpler internally, but that's just personal preference).

 The official name is "OCF-Linux", so why not call the package ocf-linux 
(and remove the OCF_SOURCE assignment)?

 /usr/include gets removed unless BR2_HAVE_DEVFILES, of course, so
doesn't it make sense to do this conditionally?
