From 24d40980b0822dff89d8ae75eedd85fa98df2cc1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sun, 12 Apr 2015 11:46:16 +0000 Subject: bcm53xx: add platform_pre_upgrade to prepare for kernel+UBI sysupgrade MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We can now detect that provided firmware contains kernel and UBI image partitions. Flashing it in a sane way (keeping erase counters) still needs to be implemented.
