Re: [PATCH] My GT-64260 enhancements

[msokolov@ivan.Harhan.ORG (Michael Sokolov)]

OK, guys, here again is my patch to bi_rec'ize the EV-64260-BP port, the common
GT-64260 code, and the GT-64260 Ethernet driver in linuxppc_2_4_devel (against
2_4_devel because it adds two new bi_recs to the master official bi_rec list in
bootinfo.h) with all controversial parts removed, just the bi_rec'ization.

I ask Matt Porter, the maintainer listed in linuxppc_2_4_devel/MAINTAINERS to
either push this patch into linuxppc_2_4_devel or give a good reason not to.
