  80. - add support for NETTA and NETPHONE boards; fix NETVIA board

  82. (These displays are serial and not suitable for using a normal
  83. framebuffer console on them)
  84. - add infrastructure needed in order to POST any DSPs in a board
  85. - improve and fix various things in the MPC8xx FEC driver:
  86. 1. The new 87x and 88x series of processors have two FECs,
  87. and the new driver supports them both.
  88. 2. Another change in the 87x/88x series is support for
  89. the RMII (Reduced MII) interface. However numerous
  90. changes are needed to make it work since the PHYs
  91. are connected to the same lines. That means that
  92. you have to address them correctly over the MII
  93. interface.
  94. 3. We now correctly match the MII/RMII interface
  95. configuration to what the PHY reports.
  96. - Fix problem when readingthe MII status register. Due to the
  97. internal design of many PHYs you have to read the register
  98. twice. The problem is more apparent in 10Mbit mode.
  99. - add new mode ".jffs2s" for reading from a NAND device: it just
  100. skips over bad blocks.
  101. - add networking support for VLANs (802.1q), and CDP (Cisco
  102. Discovery Protocol)
  103. - some minor patches / cleanup
  104. * Patch by Yuli Barcohen, 28 Mar 2004:
  105. - Add support for MPC8272 family including MPC8247/8248/8271/8272
  106. - Add support for MPC8272ADS evaluation board (another flavour of MPC8260ADS)
  107. - Change configuration method for MPC8260ADS family
  108. * add startup code to clear the BSS of standalone applications
  109. * Fix if / elif handling bug in HUSH shell
