Extending U-Boot support for Orion SoC

Overview

The Orion family of SoCs includes the following machines:

  • Buffalo/Revolution Kurbox Pro
  • Buffalo/Revolution Linkstation Mini
  • Buffalo/Revolution Terastation Pro II/Live
  • Lacie ED Mini V2
  • Lacie Internet Space V1 (V2 uses kirkwood)
  • Lacie 2Big
  • Lacie 5Big
  • Lacie d2 Network
  • Lacie Big Disk Network
  • Marvell Orion-2 Development Board, Marvell Orion-VoIP FXO, Marvell Orion-VoIP GE, Marvell Orion-NAS Reference Design, Marvell Orion-1-90 AP GE Reference Design
  • Maxtor Shared Storage II
  • QNAP TS-109/TS-209
  • QNAP TS-409
  • Technologic Systems TS-78xx

The u-boot-lacie git repo

This repo provides two branches:

  • master is kept up-to-date by merging the master branches of custodian repo that have orion5x-related commits.
  • testing is master plus patches that have not yet made it into any custodian's u-boot repo.

WARNING: testing is volatile: it may roll back on a patch that eventually proved bad, or move sideways from one version of a patch to another. Its history will be shaky. Hey, this is a testing branch. On the other hand, master will only be a merge of custodian trees, so you can reasonably expect it to contain commits that will end up in mainline u-boot.

The LaCie stock U-Boot comes with a huge limitation. The boot sequence is hardcoded within the U-Boot binary. At reset, U-Boot reinitialize the boot environment variables with the built-in ones. As a consequence, the LaCie system layout (or partition map) can't be changed. By default, U-Boot will load the Linux kernel from partition 10 (update) or from partition 6 as a fallback (default).

This section present step by step how to update the stock U-Boot with a mainline version. Both a serial or a network console can be used to connect to U-Boot. For this how-to, the netconsole way is preferred because the user don't have to build/buy a serial cable.

  • Run clunc and connect to the LaCie U-Boot console.
$ ./clunc -i <NAS_IP>
  • Setup a tftp server and install the new u-boot image in the tftp directory (could be /var/tftpboot).
$ wget ftp://ftp.lacie-nas.org/u-boot/u-boot-netspace_v2.kwb -O /var/tftpboot/u-boot-netspace_v2.kwb
  • Configure some U-Boot network environment variables. In the following example, replace ${serverip} with the tftp server IP address and replace ${ipaddr} with a valid and free IP address.
Marvell>> setenv ipaddr ${ipaddr}; setenv serverip ${serverip}
  • Flash the new U-Boot image.
Marvell>> bubt u-boot-netspace_v2.kwb

  • Restart.
Marvell>> reset
  • Install the U-Boot netconsole tool.

Note that U-Boot mainline don't provide a magic packet mechanism to configure the IP address. It means that clunc becomes useless from this point. The netconsole configuration rely on some environment variables: ipaddr, ncip, stdin, stdout and stderr (for more information, please refer to the file README.NetConsole included in U-Boot sources). After the update, this variables will be initialized with the default (or built-in) values: the IP address is 192.168.1.111 and the netconsole is configured to broadcast messages. As a consequence, the server IP must belong to the subnetwork 192.168.1.0. Moreover netcat don't handle the broadcast messages. Instead, the U-Boot tools netconsole and ncb must be used.

  • Connect to U-Boot via netconsole and interrupt boot process (Ctrl-C).
$ ./tools/netconsole 192.168.1.111
