Oh please study this and submit a patch, I believe at least Pavel (CCed) would be glad to see it in :-) > > Perhaps memory/object-size is an issue?

Well the porting might be quite a long run indeed, but basic booting from this should not be that hard. Besides the code would be fairy separate, so it should be OK. > Anyone already attempted such a project? Any resources available for such > porting? Will I even be able to run my own version of uboot on the Cubox? I don't know, sorry. > > Lund Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
