+ 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.
