-/*
- * Fast Ethernet Controller (FEC) driver for Motorola MPC8xx.
- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * This version of the driver is specific to the FADS implementation,
- * since the board contains control registers external to the processor
- * for the control of the LevelOne LXT970 transceiver.  The MPC860T manual
- * describes connections using the internal parallel port I/O, which
- * is basically all of Port D.
- *
- * Includes support for the following PHYs: QS6612, LXT970, LXT971/2.
- *
- * Right now, I am very wasteful with the buffers.  I allocate memory
- * pages and then divide them into 2K frame buffers.  This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets.
- *
- * Much better multiple PHY support by Magnus Damm.
- * Copyright (c) 2000 Ericsson Radio Systems AB.
- *
- * Make use of MII for PHY control configurable.
- * Some fixes.
- * Copyright (c) 2000-2002 Wolfgang Denk, DENX Software Engineering.
- *
- * Support for AMD AM79C874 added.
