-====== Extending U-Boot support for Orion SoC  ======
+====== U-Boot support for Orion SoCs  ======
 ===== Overview =====
-The Orion family of SoCs includes the following machines:
+See our [[uboot|U-Boot main page]].
-  * Buffalo/Revolution Kurbox Pro
+===== To-do list =====
-  * 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
-===== Repository =====
+   * adapt orion5x / edminiv2 or relocation (wip in -next)
+   * add initial support for net5big (based upon reloc adaptation)
-Sources are available in the [[http://git-scm.com|Git]] repository: [[http://git.lacie-nas.org/?p=u-boot-lacie.git;a=summary|u-boot-lacie.git]]. At least, the following branches should be availables:
+   * add initial support for net2big (based upon reloc adaptation)
+   * add I2C support to net5big
-  * **stable** is used to build the images distributed via a [[ftp://lacie-nas.org/u-boot|FTP repository]].
+   * add PCI support to net5big
-  * **master** is a development branch, holding the patches waiting to be merged mainline.
+   * add SATA over PCI support to net5big
-Checkout command:
-  git clone http://git.lacie-nas.org/u-boot-lacie.git
-or
-  git clone git://lacie-nas.org/u-boot-lacie.git
-===== Build =====
-To compile U-Boot images, you could use the following commands (toolchain path, cross-compiler and board names to be replaced):
-  PATH=/usr/local/x-tools/arm-2010q1/bin/:$PATH CROSS_COMPILE=arm-none-eabi- make netspace_v2_config
-  PATH=/usr/local/x-tools/arm-2010q1/bin/:$PATH CROSS_COMPILE=arm-none-eabi- make u-boot.kwb
-===== Downloads =====
-For the supported boards, some pre-compiled U-Boot images are availables in the [[ftp://lacie-nas.org/u-boot|FTP repository]].
-===== Install from a LaCie stock U-Boot =====
-==== Why ? ====
-  * The LaCie stock U-Boot comes with a huge limitation. At reset, U-Boot reinitialize the boot environment variables (stored in Flash) with some built-in values. This includes the boot commands sequence. 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).
-  * Save flash size (a LaCie U-Boot image size is ~450KB against ~230KB for a mainline one).
-  * Boot reliably from USB.
-  * Some command line enhancements: history, completion, scripting ...
-  * Be able to add a new feature.
-==== Update step by step ====
-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.
-=== Preparations ===
-  * Get [[CLUNC|CLUNC]]
-  * Get U-Boot netconsole utility
-  * Enable a TFTP server
-  * Install the new u-boot image in the TFTP root 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
-=== Run CLUNC and connect to the LaCie U-Boot console ===

-  **Warning**
-  If U-Boot Endiannes is going to change (LE->BE or BE->LE), Then Env parameters should be overriden..
-  Override Env parameters? (y/n) n
-  Erase 0 - 125 sectors...

-  Copy to Flash... done
-  Protect Flash Monitor space
-=== 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|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
