  860. - add infrastructure needed in order to POST any DSPs in a board
  861. - improve and fix various things in the MPC8xx FEC driver:
  862. 1. The new 87x and 88x series of processors have two FECs,
  863. and the new driver supports them both.
  864. 2. Another change in the 87x/88x series is support for
  865. the RMII (Reduced MII) interface. However numerous
  866. changes are needed to make it work since the PHYs
  867. are connected to the same lines. That means that
  868. you have to address them correctly over the MII
  869. interface.
  870. 3. We now correctly match the MII/RMII interface
  871. configuration to what the PHY reports.
  872. - Fix problem when readingthe MII status register. Due to the
  873. internal design of many PHYs you have to read the register
  874. twice. The problem is more apparent in 10Mbit mode.
  875. - add new mode ".jffs2s" for reading from a NAND device: it just
  876. skips over bad blocks.
  877. - add networking support for VLANs (802.1q), and CDP (Cisco
  878. Discovery Protocol)
  879. - some minor patches / cleanup
  880. * Patch by Yuli Barcohen, 28 Mar 2004:

  1962. give an initial value to the OBJCFLAGS make variable
  1963. - 8260 i2c enhancement:
  1964. o correctly extends the timeout depending on the size of all
  1965. queued messages for both transmit and receive

  1967. o ensures that the error callback is done for all queued tx
  1968. and rx messages
