ARMV4I isn't a processor, so it can't be a supported processor. And if you are looking for the support kind of support, then the question is whether the supplier, to whom you pay money, provides support. They should be able to answer the question about which processors they support.
If you buy a board with a BSP, then you should ask the question of your board supplier; you can try that even if you are not buying a BSP.
I'm sorry I can't provide you with a better answer based on this information, but you didn't get an answer here http://www.programmersheaven.com/mb/...ssor---armv4i/
either, so you may wish to ask a reformulated question.
