Fix TSEC driver: avoid crashes if PHY is not attached

to a TSEC (e.g. a switch is connected via RMII) or
if the PHY is defective/incorrectly configured.

     Added support for Multi-Image files that contain a device tree
-    
+
     If a Multi-Image file contains a third image we try to use it as a
     device tree.  The device tree image is assumed to be uncompressed in the
     image file.	 We automatically allocate space for the device tree in memory
     and provide an 8k pad to allow more than a reasonable amount of growth.

     Additionally, a device tree that was contained in flash will now automatically

     Add ATSTK1000 and ATSTK1002 board support
     Patch by Haavard Skinnemoen, 06 Sep 2006
-

     This patch adds support for the ATSTK1000 with the ATSTK1002 CPU
     daughterboard.

     ATSTK1000 is a full-featured development board for AT32AP CPUs. It
     has two ethernet ports, a high quality QVGA LCD panel, a loudspeaker,
     and connectors for USART, PS/2, VGA, USB, MMC/SD cards and
     CompactFlash cards. For more information, please see this page:

     Add common serial driver for Atmel AT32 and AT91 chips
     Patch by Haavard Skinnemoen, 06 Sep 2006
-

     This is a first attempt at creating a common serial driver for Atmel
     chips. For now, it supports the AT32AP7000 AVR32 chip, but it should
     be possible to support AT91RM9200 and other ARM-based chips with some
     minor modifications.

     Add AT32AP CPU and AT32AP7000 SoC support
     Patch by Haavard Skinnemoen, 06 Sep 2006
-    
+
     This patch adds support for the AT32AP CPU family and the AT32AP7000
     chip, which is the first chip implementing the AVR32 architecture.
-    
+
     The AT32AP CPU core is a high-performance implementation featuring a
     7-stage pipeline, separate instruction- and data caches, and a MMU.
     For more information, please see the "AVR32 AP Technical Reference":

     http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf

     In addition to this, the AT32AP7000 chip comes with a large set of
     integrated peripherals, many of which are shared with the AT91 series
     of ARM-based microcontrollers from Atmel. Full data sheet is
     available here:

     Add support for reading and writing mac addresses to or from ID EEPROM.
-    
+
     Added code for reading and writing Mac addresses to/from ID EEPROM(0x57).
     With attached patch, we can use command "mac/mac read/mac save/"
     to read and write EEPROM under u-boot prompt.
-    
+
     U-boot will calculate the checksum of EEPROM while bootup,
     if it is right, then u-boot will check whether the mac address
     of eTSEC0/1/2/3 is availalbe (non-zero).
-    
+
     If there is mac address availabe in EEPROM, u-boot will use it,
     otherewise, u-boot will use the mac address defined in
     MPC8641HPCN.h. This matches the requirement to set unique mac address
     for each TSEC port.
