Subject: [PATCH 1/4] powerpc/crypto: rework Kconfig
Date: Thu, 19 Jul 2012 09:42:38 -0500 [thread overview]
Message-ID: <1342708961-28587-2-git-send-email-sjenning@linux.vnet.ibm.com> (raw)
In-Reply-To: <1342708961-28587-1-git-send-email-sjenning@linux.vnet.ibm.com>
This patch creates a new submenu for the NX cryptographic
hardware accelerator and breaks the NX options into their own
Kconfig file under drivers/crypto/nx/Kconfig.
This will permit additional NX functionality to be easily
and more cleanly added in the future without touching
drivers/crypto/Makefile|Kconfig.
