This is a set of kernel options I've come up with mostly cribbing from chrome os's kernel config snippet. We also build an lzma kernel, as uncompressed kernel is big but lzma is the only compression supported by the bootloader. With that image, we have to pack it into a FIT formatted image+dtb blob. CONFIG_SUNRPC_DEBUG is added so that you can set "nfsrootdebug" to figure out what's going wrong with your nfs mount (mine were "both the tcp and nfsvers options were required, and don't try to use 'default' as the root path to defer to DHCP's answer because otherwise you get /tftpboot/default, just use an empty root path which doesn't prepend /tftpboot.")
