image: add support for EROFS rootfs image generation
Add support for generating EROFS rootfs images. The EROFS filesystem can offer competitive I/O performance while minimizing final image size when using the MicroLZMA compressor. Target platform: linux-x86_generic (target-i386_pentium4_musl) Filesystem Image Size ============= ========== root.erofs 4882432 root.ext4 109051904 root.squashfs 4903302 Co-Developed-by: Gao Xiang <hsiangkao@linux.alibaba.com> Signed-off-by: Gao Xiang <hsiangkao@linux.alibaba.com> Link: https://github.com/openwrt/openwrt/pull/19244 Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
