From ff8648f29fe58c2d94d32a076d2de7b92be4b485 Mon Sep 17 00:00:00 2001 From: Kurt Kanzenbach Date: Mon, 13 Aug 2018 09:18:46 +0200 Subject: mtd: rawnand: fsl_ifc: fixup SRAM init for newer ctrl versions Newer versions of the IFC controller use a different method of initializing the internal SRAM: Instead of reading from flash, a bit in the NAND configuration register has to be set in order to trigger the self-initializing process.
