* Patch by Thomas Frieden, 13 Nov 2002:

  Add code for AmigaOne board
  (preliminary merge to U-Boot, still WIP)

* Patch by Jon Diekema, 12 Nov 2002:
  - Adding URL for IEEE OUI lookup
  - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
    being defined.
  - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
    root-on-nfs macros are designed to switch how the default boot
    method gets defined.

+tm  - Timer object to start timing with
+
+REMARKS:
+Starts the Long Period Zen Timer counting. Once you have started the timer,
+you can stop it with LZTimerOff or you can latch the current count with
+LZTimerLap.
+
+The Long Period Zen Timer uses a number of different high precision timing
+mechanisms to obtain microsecond accurate timings results whenever possible.
+The following different techniques are used depending on the operating
+system, runtime environment and CPU on the target machine. If the target
+system has a Pentium CPU installed which supports the Read Time Stamp
+Counter instruction (RDTSC), the Zen Timer library will use this to
+obtain the maximum timing precision available.
+
+Under 32-bit Windows, if the Pentium RDTSC instruction is not available, we
+first try to use the Win32 QueryPerformanceCounter API, and if that is not
+available we fall back on the timeGetTime API which is always supported.
+
+Under 32-bit DOS, if the Pentium RDTSC instruction is not available, we
+then do all timing using the old style 8253 timer chip. The 8253 timer
+routines provide highly accurate timings results in pure DOS mode, however
+in a DOS box under Windows or other Operating Systems the virtualization
+of the timer can produce inaccurate results.
+
+Note: Because the Long Period Zen Timer stores the results in a 32-bit
+      unsigned integer, you can only time periods of up to 2^32 microseconds,
+      or about 1hr 20mins. For timing longer periods use the Ultra Long
+      Period Zen Timer.

+
+REMARKS:
+Starts the Ultra Long Period Zen Timer counting. Once you have started the
+timer, you can stop it with ULZTimerOff or you can latch the current count
+with ULZTimerLap.
+
+The Ultra Long Period Zen Timer uses the available operating system services
+to obtain accurate timings results with as much precision as the operating
+system provides, but with enough granularity to time longer periods of
+time than the Long Period Zen Timer. Note that the resolution of the timer
+ticks is not constant between different platforms, and you should use the
+ULZTimerResolution function to determine the number of seconds in a single
+tick of the timer, and use this to convert the timer counts to seconds.
+
+Under 32-bit Windows, we use the timeGetTime function which provides a
+resolution of 1 millisecond (0.001 of a second). Given that the timer
+count is returned as an unsigned 32-bit integer, this we can time intervals
+that are a maximum of 2^32 milliseconds in length (or about 1,200 hours or
+50 days!).
+
+Under 32-bit DOS, we use the system timer tick which runs at 18.2 times per
+second. Given that the timer count is returned as an unsigned 32-bit integer,
+this we can time intervals that are a maximum of 2^32 * (1/18.2) in length
+(or about 65,550 hours or 2731 days!).
