When I said attention, I meant more as a platform, I realise it's not
quite a Tier 1 arch but even arm has it's own category etc for problem
reports - not attempting to devalue the enormous amount of work both you
and others do, not just for MIPS but in general.
I guess really I just expected the same as seen for example amd64...
Either way, overly facetious comment - no offense intended and apologies
if it did offend.
Thanks
