OK gotcha.  Will this be a suzaku platform option, or microblaze arch 
option?  If it's microblaze-wide, can you do it so the current romfs 
behaviour is the default?

Sounds good - again, my only request is for it to keep current platforms 
working by defalut.

OK so I couldn't help myself - the restructure patch applies cleanly and 
at still makes a kernel on my configuration.  I won't be able to test it 
on a board until Tuesday, but if Greg or David are reading this then I'm 
happy for it to go straight in.

Thanks - it's nice, a 4 day weekend, and here in Brisbane at least we've 
had great weather for it.

Cheers,
