From 98089bb8ba82e41f09e73c6492ba9183cb44e614 Mon Sep 17 00:00:00 2001 From: Chris Blake Date: Mon, 24 Jun 2019 06:32:45 -0500 Subject: [PATCH] mpc85xx: Use uncompressed kernel on the HiveAP-330 It seems that newer builds of OpenWRT have a gzip kernel larger than 2MB~, which for some reason fails to boot on this board. However, we have 8MB of kernel space and currently the uncompressed kernel is 6.5MB~, so we have some space to grow until a better solution is worked out.
