In our company, network is much more feasible than other media like USB stick,
so that we can easily run some external applications or OS loaders. And USB
stick is also restricted for security concerns.

Anyway, appending a build flag is still acceptable for us, for we can add the
flag in our internal build script for development. But patch 1/2 is still
needed, or else tftp will initialize failed even if we manually set the define
flag.
