From b985f34f33e07477842d430a4ef2261d1e63fd6b Mon Sep 17 00:00:00 2001 From: John Thomson Date: Thu, 15 Oct 2020 19:27:55 +1000 Subject: [PATCH] mt7621: mikrotik: use vmlinuz (zBoot ELF) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - minimal built initramfs: 11MB vmlinux ELF -> 4.5MB vmlinuz - ~5 seconds for kernel decompression, which was equivalent to the additional time to load the uncompressed ELF from SPI NOR. - Removes requirement for lzma-loader, which may have been causing some image builds to fail to boot on Mikrotik mt7621.
