[U-Boot] [PATCH 1/4] nfs: convert supported_nfs_versions bitfield to an enum

Dear Christian,

Hm... as you are putting efforts into NFS support...

Here comes a more general question:

I wonder if it's worth the work on NFS at all, or if we should
remove NFS support from U-Boot alltogether?

1) We support only NFS v2 (and v3) in U-Boot, and most standard Linux
   distros support only v4 in their default configurations.

2) We support only UDP, but most standard Linux distros support only
   TCP in their default configurations (see [1])

   [1] http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=commitdiff;h=fbd7623dd8d5e418e7cb369d4026d5368f7c46a6

Try a NFS download from any recent Linux distro (i. e. one including
nfs-utils 2.3.1 or later)...


I feel a half-way solution is unsatisfactory, but the way for the
Real Thing (TM) is a pretty long one...

The fact that nobody compained yet that NFS stopped working fo him
suggests that there are only very, very few users of NFS at all.
If one of these is willing to step up and fix this for real, he is
of course more than welcome.  But if not - should we not remove the
more or less obsolete code?

Best regards,

Wolfgang Denk
