From 0c0bb629992d3cc2fe277a2348e8cf70fa429567 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Wed, 6 Jun 2018 00:35:17 +0200 Subject: [PATCH] ar71xx: switch CPE/WBS 210/510 to okli-loader We recently increased the kernel partition size of the CPE/WBS 210/510. This works fine for new installations of the factory image, but on sysupgrades, the partition table read by the bootloader is not adjusted. This limits the maximum size of the kernel loaded by the bootloader to the old partition size. While adjusting the partition table would be a cleanest solution, such a migration would have to happen before an upgrade to a new version with a newer kernel. This is error-prone and would require a two-step upgrade, as we mark the partition table partition read-only. Instead, switch from the lzma-loader with embedded kernel to the okli-loader, so only the tiny lzma-loader is loaded by the bootloader as "kernel", and the lzma-loader will then load the rest of the kernel by itself.
