From 3b1261224aa0313ab8c155d3a4679e598a04d9a6 Mon Sep 17 00:00:00 2001 From: Jan Hoffmann Date: Sat, 23 Jul 2022 22:53:17 +0200 Subject: kernel: mtdsplit: add support for H3C VFS filesystem The bootloader on some H3C devices (for example HPE 1920 switches) only supports booting from flash by reading an image from an "VFS" filesystem which spans most of the available flash. The filesystem size is hard- coded in the bootloader. However, as long as no write operations are performed in the bootloader menu, it is sufficient if the start of the partition contains a valid filesystem with the kernel image. This mtdsplit parser reads the size and location of the kernel image and finds the location of the rootfs stored after it. It assumes that the filesystem image matches the layout of one generated by mkh3cvfs, with a filename of "openwrt-kernel.bin" for the kernel image.
