Wow, I knew h/w designers are creative, but _that_ creative ;) Cheers Detlev -- I have always observed that the pretensions of all people are in exact inverse ratio to their merits; this is one of the axioms of morals. -- Joseph Lagrange -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-40 Fax: (+49)-8142-66989-80 Email: d...@denx.de _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
