From: John Thomson Date: Wed, 16 Oct 2024 02:51:22 +0000 (+1000) Subject: kernel: mtdsplit_minor: accept bootimage filename X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=36834ea3403d05b6beab3a2efc3f00f097e58c81;p=openwrt%2Fstaging%2Fwigyori.git kernel: mtdsplit_minor: accept bootimage filename RouterBOOT v7 on NOR devices no longer accepts the YAFFS kernel ELF method of booting. It will accept an NPK image named bootimage. Adjust mtdsplit_minor to accept this second possible boot file name. Use the conservative value of 127 for YAFFS max name length (used when YAFFS compiled with unicode support) vs 255.
