* Patches by Pantelis Antoniou, 16 Apr 2004:
  - add support for a new version of an Intracom board and fix
    various other things on others.
  - add verify support to the crc32 command (define
    CONFIG_CRC32_VERIFY to enable it)
  - fix FEC driver for MPC8xx systems:
    1. fix compilation problems for boards that use dynamic
       allocation of DPRAM
    2. shut down FEC after network transfers
  - HUSH parser fixes:
    1. A new test command was added. This is a simplified version of
       the one in the bourne shell.
    2. A new exit command was added which terminates the current
       executing script.
    3. Fixed handing of $? (exit code of last executed command)

* Patch by George G. Davis, 02 Apr 2004:
  add support for Intel Assabet board

* Patch by Stephen Williams, 01 Apr 2004:
  Add support for Picture Elements JSE board

* Patch by Christian Pell, 01 Apr 2004:
  Add CompactFlash support for PXA systems.

* Patches by Pantelis Antoniou, 30 Mar 2004:
  - add auto-complete support to the U-Boot CLI
  - add support for NETTA and NETPHONE boards; fix NETVIA board
  - add support for the Epson 156x series of graphical displays
    (These displays are serial and not suitable for using a normal
    framebuffer console on them)
  - add infrastructure needed in order to POST any DSPs in a board
  - improve and fix various things in the MPC8xx FEC driver:
    1. The new 87x and 88x series of processors have two FECs,
       and the new driver supports them both.
    2. Another change in the 87x/88x series is support for
       the RMII (Reduced MII) interface. However numerous
       changes are needed to make it work since the PHYs
       are connected to the same lines. That means that
       you have to address them correctly over the MII
       interface.
    3. We now correctly match the MII/RMII interface
       configuration to what the PHY reports.
  - Fix problem when readingthe MII status register. Due to the
    internal design of many PHYs you have to read the register
    twice. The problem is more apparent in 10Mbit mode.
  - add new mode ".jffs2s" for reading from a NAND device: it just
    skips over bad blocks.
  - add networking support for VLANs (802.1q), and CDP (Cisco
    Discovery Protocol)
  - some minor patches / cleanup

* Patch by Yuli Barcohen, 28 Mar 2004:
  - Add support for MPC8272 family including MPC8247/8248/8271/8272

* Patch by Anders Larsen, 09 Jan 2004:

  ARM memory layout fixes: the abort-stack is now set up in the
  correct RAM area, and the BSS is zeroed out as it should be.

  Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
  of the linker scripts are replaced by '__bss_start' and '_end',
  resp., which is a further step to eliminate unnecessary differences
  between the implementation of the CPU architectures.

* Patch by liang a lei, 9 Jan 2004:

    linker script, selected via the LDSCRIPT, make variable, and to
    give an initial value to the OBJCFLAGS make variable
  - 8260 i2c enhancement:
    o correctly extends the timeout depending on the size of all
      queued messages for both transmit and receive
    o will not continue with receive if transmit times out
    o ensures that the error callback is done for all queued tx
      and rx messages
    o correctly detects both tx and rx timeouts, only delivers one to
      the callback, and does not overwrite an earlier error
    o logic in i2c_probe now correct
  - add "vprintf()" function so that "panic()" function can be
    technically correct
  - many Hymod board changes

  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by
    writing beyond the block boundaries.
  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.

  processing the receive buffers slower than the network controller
  was filling them.
