From 7d6e73810dec029678a0d14a3f47485d4025520e Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Wed, 16 Nov 2016 13:45:35 +1030 Subject: arch_flash_arm: Don't assume mtd labels are short pflash relies on arch_flash_arm parsing /proc/mtd to discover the pnor partition. It helpfully uses strcasestr so it can handle the string changing, which is what has happened as we moved to upstream compliant mtd device tree bindings. We currently have a string like this: dev: size erasesize name mtd0: 00060000 00001000 "u-boot" mtd1: 00020000 00001000 "u-boot-env" mtd2: 00280000 00001000 "kernel" mtd3: 001c0000 00001000 "initramfs" mtd4: 01740000 00001000 "rofs" mtd5: 00400000 00001000 "rwfs" mtd6: 02000000 00001000 "1e620000.flash-controller:flash@1" mtd7: 08000000 00001000 "1e630000.flash-controller:pnor@0" Unfortunately arch_flash_arm assumes the string will be at most 50 characters. That's right before the label we're looking for starts so we ignore that line and keep searching. Fix it by allowing for a 255 character line.
