Additionally to Wolfgangs comments, let me make a few observations here. In a different project I also thought on how to implement functionality compared to what you try to achieve and in the end I got the impression that this is a very good chance to introduce a real device model into U-Boot. We have been thinking about this for a long time[1] but nobody came around hacking on it yet. If you check the BOF page, you can see that this will also open up a way to do a dynamic driver configuration, e.g. by device tree. This is one direction we really need to cover somehow - sooner or later. What do you think - do you want to go the extra distance? For a transitional time, I think we can also live with two serial driver implementatinos - after all, we have 5 "mpsc.c" files in the tree currently, so every chance for a cleanup is welcome :) Cheers Detlev [1] http://www.denx.de/wiki/view/U-Boot/OLSUbootBOF -- ["From 2.4 to 2.6 to 2.7" discussing release numbering of the Linux kernel] Let the bike-shed-painting begin. -- Linus Torvalds -- 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
