* 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.
