From 9905e77edaa9b4a43285e587317c600ffa7be7ca Mon Sep 17 00:00:00 2001 From: Arseniy Krasnov Date: Mon, 26 Aug 2024 16:17:08 +0300 Subject: mtd: rawnand: nand_base: support for 'NAND_IS_BOOT_MEDIUM' flag Based on Linux kernel: commit f922bd798bb9 ("mtd: rawnand: add an option to specify NAND chip as a boot device") Allow to define a NAND chip as a boot device. This can be helpful for the selection of the ECC algorithm and strength in case the boot ROM supports only a subset of controller provided options.
