From 02ba194feacb994d6ed8dd60550a2dcf213e256d Mon Sep 17 00:00:00 2001 From: David Jander Date: Tue, 3 Dec 2024 11:38:37 +0100 Subject: mtd: mchp48l640: add support for Fujitsu MB85RS128TY FRAM The Fujitsu FRAM chips use the same command set as Microchip EERAM. The only differences are that the Fujitsu FRAM chips don't really have a page size limit, nor do they automatically reset the WEL bit.
