Subject: [PATCH 07/13] lightnvm: check for NAND flash and its type
Date: Mon, 16 Nov 2015 15:34:41 +0100	[thread overview]
Message-ID: <1447684487-25539-8-git-send-email-m@bjorling.me> (raw)
In-Reply-To: <1447684487-25539-1-git-send-email-m@bjorling.me>

Only NAND flash with SLC and MLC is supported. Make sure to not try to
initialize TLC memory or other non-volatile memory types.
