Thomas Petazzoni - April 17, 2012, 2:45 p.m.
The support for Xtensa has been added in July 2009, and no updates
have ever been done to it, and it requires some special handling, in
gcc/gdb, has some special Perl scripts, etc.

As discussed on IRC, I would prefer to simply mark Xtensa as deprecated
for now, and then remove in the next cycle if nothing happens.

I am fine with this decision, and will send a patch that implements it.
My patch removing Xtensa support was mainly to get the discussion
started.

Thanks,

Thomas

Good. I already added the BR2_DEPRECATED (555c2585b).

Thanks for the reprieve.  How far is that "next cycle"?

-# example, if you want to adjust the permissions on a particular file
-# you can just add an entry like:

-# and (assuming the file /sbin/foobar exists) it will be made setuid
-# root (regardless of what its permissions are on the host filesystem.
-# Furthermore, you can use a single table entry to create a many device
-# minors.  For example, if I wanted to create /dev/hda and /dev/hda[0-15]
-# I could just use the following two table entries:
