  • f33665d93   [MTD] Support combined RedBoot FIS directory and configuration area ... Browse Code »

    RedBoot supports storing the FIS directory and the RedBoot
    configuration area in the same block of flash memory. This is
    not the most common RedBoot configuration, but it is used on
    commercially available boards supported by the kernel.

    A recent patch to mtd/redboot.c (http://lkml.org/lkml/2006/3/20/410)
    which corrected the skipping of deleted table entries has exposed the
    latent problem of the kernel redboot parser running off the end of the
    FIS directory and interpreting the RedBoot configuration information
    as table entries.

    This patch terminates the table parsing when the first truly empty
    entry is found (table entry deletion only clears the first byte of the
    name, so two cleared bytes in a row indicates the end of the table),
    thereby supporting the combined redboot FIS directory and RedBoot
    configuration information flash layout scenario.

  • b020bb7d3   [MTD] Fix build warnings in RedBoot MTD partition parser. ... Browse Code »

    Fix build warnings from drivers/mtd/redboot.c due to
    use of `unsigned long` in `struct fis_image_desc` for
    fields being passed to swab32s() which expects __u32 *

    Change the entries to uint32_t to make them compatible
    with the swab32s() function

  • 84e699e6e   [PATCH] mtd/redboot: Handle holes in fis table ... Browse Code »

    Redboot simply sets the first character of a fis entry to 0xff on "fis
    delete". The kernel redboot parser stops parsing on such an entry, and
    without this patch any entries after a deleted image would not be detected.

  • 9cff3372b   [PATCH] drivers/mtd/redboot.c: recognise a foreign byte sex partition table ... Browse Code »

    The RedBoot boot loader writes flash partition tables containing native
    byte sex 32 bit values. When booting an opposite byte sex kernel (e.g. an
    LE kernel from BE RedBoot) the current MTD driver fails to handle the
    partition table and therefore is unable to generate the correct partition
    map for the flash.

    So far as I am aware this problem is ARM specific, because only ARM
    supports software change of the CPU (memory system) byte sex, however the
    partition table parsing is in generic MTD code. The patch below has been
    tested on NSLU2 (an IXP4XX based system) with a patch,
    10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM
    specific) required to make the maps/ixp4xx.c driver work with an LE kernel.

    Builds of the patched system are in the 'unstable' release of OpenSlug and
    UcSlugC available from www.nslu2-linux.org. These builds are BE, the
    archives at www.nslu2-linux.org and www.handhelds.org (see
    monotone.vanille.de) can be built LE (currently DISTRO targets
    nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf,
    nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested
    extensively will both BE and LE systems on the NSLU2 (including swapping
    between BE and LE by reflashing from both RedBoot and Linux).

    The patch recognises that the FIS directory (the partition table) is
    byte-reversed by examining the partition table size, which is known to be
    one erase block (this is an assumption made elsewhere in redboot.c). If
    the size matches the erase block after byte swapping the value then
    byte-reversal is assumed, if not no further action is taken. The patched
    code is fail safe; should redboot.c be changed to support a partition table
    with a modified size field the test will fail and the partition table will
    be assumed to have the host byte sex.

    If byte-reversal is detected the patch byte swaps the remainder of the 32
    bit fields in the copy of the table; this copy is then used to set up the
    MTD partition map.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
