Subject: [PATCH 0/7] Basic support for Marvell Armada 370/XP SoC
Date: Fri,  3 May 2013 18:51:04 +0200	[thread overview]
Message-ID: <1367599871-28479-1-git-send-email-thomas.petazzoni@free-electrons.com> (raw)

Hello,

Here is a patch set that adds basic support for the Marvell Armada 370
and Armada XP SoC. For now, the support is quite minimal, since only
the serial port is supported. However, a significant part of the work
has been the development of the tools that allow to extract/create
bootable images and to push a bootable image through the UART to the
hardware platform.

I expect to work on adding support for more devices (such as the
network interface) and possibly to add support for the older, but
popular, Marvell Kirkwood SoC family. Contributions are of course
welcome.

In detail, the patch set contains:

 * A kwbimage tool. This tool allows to extract existing bootloader
   images, and create new bootloader images. It is more or less
   similar in purpose to the kwbimage tool from U-Boot, but is capable
   of handling 'version 1' images used by Armada 370/XP, and not only
   allows to create images, but also extract images.

   A typical usage is to first extract an existing bootloader image:

    ./scripts/kwbimage -x -i <existing-image> -o <some-directory>

   As an output, you typically get 3 files: kwbimage.cfg (a text file
   that describes the configuration of the image in a format
   ressembling the one used by U-Boot), binary.0 (the binary blob that
   does the DDR3 training) and payload (the bootloader itself).

   Being able to extract an image is needed in order to get the DDR3
   training code, and re-use it with Barebox.

   An image is then later created with:

    ./scripts/kwbimage -x -i <path/to/kwbimage.cfg> -o <image>

   For each board, the kwbimage.cfg file is typically located in
   arch/arm/boards/<board-name>/. The DDR3 training code must however
   be extracted from an existing bootloader image of your board,
   usually the one provided by the board manufacturer.

 * A kwboot tool to push a bootloader through UART. It is directly
   taken from U-Boot source code, to which I've added some fixes:

   - Extend the timeouts, to actually make it work on Armada
     370/XP. This has originally been found by Willy Tarreau.

   - Ignore non-Xmodem characters, so that the original DDR3 training
     code can be used without modifications (Willy had to change it to
     make it output its messages on a different serial port, otherwise
     it was confusing the Xmodem implementation)

   - Output to stdout all the non-Xmodem characters so that if
     something goes wrong during the transfer, we have some
     informations. It also shows the messages output by the DDR3
     training code.

   - Remove the 'patch' feature that patches an image to have the UART
     type. This requires a knowledge of the header format, which is
     different between version 0 (kirkwood) and version 1 (armada
     370/xp). It is not really needed anyway since kwbimage can
     extract and create images.

 * The SoC-level code, which for now only consists in a minimal
   clocksource driver, a function to register an UART, a fixed-rate
   clock, and a function that determines the amount of RAM by looking
   at the SDRAM windows registers.

 * The board-level code for the Armada 370 Mirabox from Globalscale,
   the Armada XP OpenBlocks AX3 from Plathome and the Armada XP GP
   from Marvell.

Reviews and comments welcome!

Best regards,

Thomas
