[RFC PATCH 00/15] MIPS64 support

Hi,

Recently I've resolved a couple of issues that prevented 64bit Barebox from 
running on MIPS64 CPUs. By the way, 32bit Barebox runs on MIPS64 without any 
issues, since MIPS64 supports 32 bit addressing mode. Here is a relevant patch 
series.  This is mostly for discussion, yet some patches can be applied as is.  
Please, give your comments.

Regards,
Peter
