      Remove legacy NAND and disk on chip code. · be33b046
      Scott Wood authored
      Legacy NAND had been scheduled for removal.  Any boards that use this
      were already not building in the previous release due to an #error.
      
      The disk on chip code in common/cmd_doc.c relies on legacy NAND,
      and it has also been removed.  There is newer disk on chip code
      in drivers/mtd/nand; someone with access to hardware and sufficient
      time and motivation can try to get that working, but for now disk
      on chip is not supported.

      davinci_nand: cleanup II (CONFIG_SYS_DAVINCI_BROKEN_ECC) · 6e29ed8e
      David Brownell authored
      Remove CONFIG_SYS_DAVINCI_BROKEN_ECC option.  It's not just nasty;
      it's also unused by any current boards, and doesn't even match the
      main U-Boot distributions from TI (which use soft ECC, or 4-bit ECC
      on newer chips that support it).
      
      DaVinci GIT kernels since 2.6.24, and mainline Linux since 2.6.30,
      match non-BROKEN code paths for 1-bit HW ECC.  The BROKEN code paths
      do seem to partially match what MontaVista/TI kernels (4.0/2.6.10,
      and 5.0/2.6.18) do ... but only for small pages.  Large page support
      is really broken (and it's unclear just what software it was trying
      to match!), and the ECC layout was making three more bytes available
      for use by filesystem (or whatever) code.
      
      Since this option itself seems broken, remove it.  Add a comment
      about the MV/TI compat issue, and the most straightforward way to
      address it (should someone really need to solve it).

      Noisily disable the legacy NAND subsystem. · 99067b08
      Scott Wood authored
      Legacy NAND is marked for feature removal after April 2009 (i.e. this
      upcoming release).  There are still several boards that reference it
      (though many do so only for disk-on-chip support which has been silently
      disabled for a while now).  These boards will now fail to build
      with #error, though the code is still there if the user removes #error.
      
      The plan is to remove the code outright in the next release, along with
      any board code that refers to it (such as board/esd/common/auto_update.c).
      
      Also, remove the legacy NAND API description from README.nand.

      ARM DaVinci: Fix broken HW ECC for large page NAND. · 9b05aa78
      Hugo Villeneuve authored
      Based on original patch by Bernard Blackham <bernard@largestprime.net>
      
      U-boot's HW ECC support for large page NAND on Davinci is completely
      broken.  Some kernels, such as the 2.6.10 one supported by
      MontaVista for DaVinci, rely upon this broken behaviour as they
      share the same code for ECCs. In the existing scheme, error
      detection *might* work on large page, but error correction
      definitely does not.  Small page ECC correction works, but the
      format is not compatible with the mainline git kernel.
      
      This patch adds ECC code that matches what is currently in the
      Davinci git repository (since NAND support was added in 2.6.24).
      This makes the ECC and OOB layout written by u-boot compatible with
      Linux for both small page and large page devices and fixes ECC
      correction for large page devices.
      
      The old behaviour can be restored by defining the macro
      CFG_DAVINCI_BROKEN_ECC, which is undefined by default.
