  • 0ea6e6112   Documentation: update broken web addresses. ... Browse Code »

    Below you will find an updated version from the original series bunching all patches into one big patch
    updating broken web addresses that are located in Documentation/*
    Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
    the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
    Now there are also some addresses pointing to .spec files some are located, but some(after searching
    on the companies site)where still no where to be found. In this case I just changed the address
    to the company site this way the users can contact the company and they can locate them for the users.

  • 3fbed4c61   mflash: initial support ... Browse Code »

    This driver supports mflash IO mode for linux.

    Mflash is embedded flash drive and mainly targeted mobile and consumer
    electronic devices.

    Internally, mflash has nand flash and other hardware logics and supports 2
    different operation (ATA, IO) modes. ATA mode doesn't need any new driver
    and currently works well under standard IDE subsystem. Actually it's one
    chip SSD. IO mode is ATA-like custom mode for the host that doesn't have
    IDE interface.

    Followings are brief descriptions about IO mode.
    A. IO mode based on ATA protocol and uses some custom command. (read confirm,
    write confirm)
    B. IO mode uses SRAM bus interface.
    C. IO mode supports 4kB boot area, so host can boot from mflash.

    This driver is quitely similar to a standard ATA driver, but because of
    following reasons it is currently seperated with ATA layer.

    1. ATA layer deals standard ATA protocol. ATA layer have many low-
    level device specific interface, but data transfer keeps ATA rule.
    But, mflash IO mode doesn't.

    2. Even though currently not used in mflash driver code, mflash has
    some custom command and modes. (nand fusing, firmware patch, etc) If
    this feature supported in linux kernel, ATA layer more altered.

    3. Currently PATA platform device driver doesn't support interrupt.
    (I'm not sure) But, mflash uses interrupt (polling mode is just for
    debug).

    4. mflash is somewhat under-develop product. Even though some company
    already using mflash their own product, I think more time is needed for
    standardization of custom command and mode. That time (maybe October)
    I will talk to with ATA people. If they accept integration, I will
    integrate.
