From 99f72c0d6264661873de418868de0003fef21086 Mon Sep 17 00:00:00 2001 From: Piotr Dymacz Date: Tue, 29 Jan 2019 18:12:51 +0100 Subject: [PATCH] ipq40xx: add support for Macronix MX35LF1GE4AB SPI NAND Without a proper SPI NAND support (SPI NAND framework is available in kernel >= 4.19) the only way to make such flash working is to include it in raw/parallel NAND subsystem support and combine with mt29f staging driver. Obviously, this approach isn't going to be accepted by upstream (similar support for Winbond W25N01GV was rejected).
