Based on what you said all went well, didn't it? Basically, I think the main thing you have to configure there is flash location (in the kernel), to be able to use it via MTD. Booting from NFS or Flash is pretty much effortless, configurable via cmdli= ne. Be more specific, so we can help you more...
