[U-Boot-Users] patch to add autoload via NFS

[Masami Komiya]

The patch to add autoload via NFS after bootp or dhcp.

If you want to use, please define CONFIG_AUTOLOAD_VIA_NFS
in your configuration file.

What do you think about this patch ? (although I don't need
autoload so much.)

Best regards.

Hmm. If you do it this way you can't have autoload enabled for both
NFS and TFTP! Is that a good thing?

Is there a way the DHCP server can tell the client how to load the
file? I.e. to use tftp or nfs or something else? So you can decide
based answer from the DHCP server how to load it...

I want to enable the both. But I didn't have the idea how to decide
the protocol TFTP or NFS.

I can't find out the such keyword in the manual of dhcpd.conf.

Otherwise, to use the new environment variable like "autoload-nfs"
or "autoload-protocol" to decide the protocol.

Does anyone have the idea ?

Best regards.

The idea is already in your mail: Use the existing environment 
variable autoload like

autoload=n	-> no autoload
autoload=y	-> tftp (for historical reasons)
autoload=tftp	-> use tftp
autoload=nfs	-> use NFS

How about that?

Very nice, I agree with you.

I'll wait the other idea for a while before making.

nfs-autoload-eval-01.patch follows above.

Another simple idea is (nfs-autoload-eval-02.patch)

if (autoload==n)
   no autoload
else if (autoload==N)
   use NFS
else
   use TFTP

Thank you for your comment.

Best regards.

I will apply this patch but modify it to test for autoload==NFS.

Of course there's no reason for it, it's just our policy.

So far, anything but "n*" will enable TFTP download.  We  should  not
break this behaviour. My suggestion is:

	autoload=n*	=> suppress autoload
	autoload=NFS	=> use NFS
	anything else	=> use TFTP

If you're not part of the solution, you're part of the problem.
