Subject: [PATCH v2 1/5] mtd: rfd_ftl: allow use of MTD_RAM for testing purposes
Date: Sat, 7 Aug 2021 22:45:34 +0100 [thread overview]
Message-ID: <20210807214538.14484-2-sean@mess.org> (raw)
In-Reply-To: <20210807214538.14484-1-sean@mess.org>
This allows the rfd_ftl to be used with the mtdram module, so we can
test different mtd sizes and test the rfd_ftl on machines without a
physical nor flash device.
