Please add the following to the release-notes on armel in the upgrade section:
HP mv2120 The default u-boot settings from HP no longer work with Debian 9. Before you can upgrade to Debian 9, you have to change some settings in the u-boot configuration. The required changes are documented on the [Debian on HP mv2120](http://www.cyrius.com/debian/orion/hp/mv2120/uboot-config/) page. or if you don't want to link to an external page: HP mv2120 The default u-boot settings from HP no longer work with Debian 9. Before you can upgrade to Debian 9, you have to change some settings in the u-boot configuration. If you have serial console access to the mv2120, you can run some commands in u-boot. Simply interrupt the boot process by pressing a key and type the following: setenv loadAddr 0x0600000 setenv bootcmd 'bootext2 0,1:1,2 0x0600000 /boot/uImage /dev/sda /dev/sdb' saveenv If you don't have a serial console, you can make the changes from within Debian. Run the following commands: cat >/etc/fw_env.config <<EOF /dev/mtd0 0x00000 0x1000 0x20000 EOF fw_setenv loadAddr 0x0600000 fw_setenv bootcmd "bootext2 0,1:1,2 0x0600000 /boot/uImage /dev/sda /dev/sdb" This creates a config file so the u-boot environment can be modified and uses fw_setenv to update two boot variables. -- Martin Michlmayr http://www.cyrius.com/
