From 6507831f0e005fee670c0f01f42fd5ee8ea39181 Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Wed, 17 Jan 2018 00:21:44 +0200 Subject: [PATCH] MIPS: bcm47xx: enable ZBOOT support Enable ZBOOT support. The WRT54GL router's bootloader limits kernel size to 3 MB with the normal load address, which is a bit challenging vmlinux size with modern Linux. A compressed kernel allows booting much bigger kernels.
