+This is the readme for the Das U-Boot standalone program smc91111
+
+The main purpose of this is to manage MAC addresses on platforms
+which include the SMC91111 integrated 10/100 MAC Phy, with attached
+EEPROMs.
+
+
+Contents:
+------------------------
+1. Ensuring U-boot's MAC address can be set in hardware
+2. Running the smc91111_eeprom program
+3. Setting MAC addresses
+4. Other things you can do with this
+5. Things to be done.
+
+
+1. Ensuring U-boot's MAC address can be set in hardware
+--------------------------------------------------------------------------
+
+On the Internet - MAC addresses are very important. Short for Media
+Access Control address, a hardware address that uniquely identifies
+each node of a network. When things are not unique - bad things
+can happen.  This is why U-Boot makes it difficult to change MAC
+addresses.
+
+To find out who has a MAC address, or to purchase MAC addresses, goto
+the IEEE, at:
+http://standards.ieee.org/regauth/oui/index.shtml
+
+To change your MAC address, there can not be a MAC address predefined in
+U-Boot. To ensure that this does not occur, check your
+include/configs/<board_name>.h file, and check to see that the following
+settings are _not_ or commented out there.
+
+#define HARDCODE_MAC			1
+#define CONFIG_ETHADDR			02:80:ad:20:31:b8
+
+The purpose of HARDCODE_MAC is to hardcode the MAC address in software,
+(not what we want), or to preset it to 02:80:ad:20:31:b8 (not what we
+want either).
+
+You can check this in a running U-Boot, by doing a power cycle, then
+before U-Boot tries to do any networking, running the 'printenv' command
+
+  BOOT> printenv
+
+  ethaddr=02:80:ad:20:31:b8
+
+If you see the 'ethaddr' variable show up, like the above, you need to
+recompile U-Boot, with the above settings commented out of the
+include/configs/<board_name>.h file.
+
+2. Running the smc91111_eeprom program
+---------------------------------------------------------------------
+
+After Uboot is compiled, there should be three files of interest:
+-rwxr-xr-x    1		8806 2004-10-11 14:00 smc91111_eeprom	    <- ELF
+-rwxr-xr-x    1		3440 2004-10-11 14:00 smc91111_eeprom.bin   <- BIN
+-rwxr-xr-x    1		9524 2004-10-11 14:00 smc91111_eeprom.srec  <- SREC
+
+if there is not, check the examples/Makefile, and ensure there is something
+like for your architecture:
+
+   ifeq ($(ARCH),blackfin)
+   SREC	  += smc91111_eeprom.srec
+   BIN	  += smc91111_eeprom.bin smc91111_eeprom
+   endif
+
+To load the files: there are two methods: a) serial or b) network. Since
+it is not a good idea to start doing things on the network before the
+MAC address is set, this example will do things over serial.
+
+a) Loading the elf file via the serial port
+--------------------------------------------
+Loading the elf is very easy - just ensure that the location
+you specify things to load as is not the load address specified
+in the Makefile.
+

+
+b) Loading the binary file via the serial port
+-----------------------------------------------
+For many toolchains, the entry point is not the load point.
+The Load point is a hard coded address from the
+examples/Makefile. The entry point can be found by doing something
+like:
+
+  u-boot_1.1.1/examples> bfin-elf-objdump -d smc91111_eeprom |less
+
+  smc91111_eeprom:     file format elf32-bfin
+
+  Disassembly of section .text:
+
+  00001000 <smc91111_eeprom-0xd8>:
+      1000:
+  000010d8 <smc91111_eeprom>:
+
+You can see that the entry point (or the address that should be
+jumped to is 0x10d8). This is also the same as the entry point
+of the elf file.
+
+Now we load it to the actual load location:
+
+BOOT> loadb 0x1000
+
+## Ready for binary (kermit) download to 0x00001000 at 57600 bps...

+
+3. Setting MAC addresses
+--------------------------------------------------------------------------
+
+The MAC address can be stored in four locations:
+
+-Boot environmental variable in Flash <- can not change, without
+					  re-flashing U-boot.
+U-Boot environental variable	       <- can not change, without
+					  resetting board/U-Boot
+LAN91C111 Registers		       <- volitle
+LAN91C111 EEPROM		       <- Non Volitle
+
+If you have not activated the network, and do not have a hardcoded
+or pre-assigned MAC address in U-boot, the environmental variables
+should be blank, and allow you to set things one time.
+
+To set the EEPROM MAC address to 12:34:56:78:9A:BC

+4. Other things that you can do
+--------------------------------------------------------------------------
+After the stand alone application is running, there are a few options:
+ - P : Print the MAC
+ - D : Dump the LAN91C111 EEPROM contents
+ - M : Dump the LAN91C111 MAC contents
+ - C : Copies the MAC address from the EEPROM to the LAN91C111
+ - W : Write a register in the EEPROM or in the MAC
