[Buildroot] [PATCH 22/22] xtensa: remove support for this architecture

Thomas Petazzoni thomas.petazzoni at free-electrons.com
Tue Apr 17 14:45:34 UTC 2012


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.

-# When building a target filesystem, it is desirable to not have to
-# become root and then run 'mknod' a thousand times.  Using a device 
-# table you can create device nodes and directories "on the fly".
-#
-# This is a sample device table file for use with genext2fs.  You can
-# do all sorts of interesting things with a device table file.  For
-# example, if you want to adjust the permissions on a particular file
-# you can just add an entry like:
-#   /sbin/foobar        f       2755    0       0       -       -       -       -       -
-# 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:
-#   /dev/hda    b       640     0       0       3       0       0       0       -
-#   /dev/hda    b       640     0       0       3       1       1       1       15
-# 
-# Device table entries take the form of:
-# <name>    <type>      <mode>  <uid>   <gid>   <major> <minor> <start> <inc>   <count>
-# where name is the file name,  type can be one of: 
-#       f       A regular file
-#       d       Directory
-#       c       Character special device file
-#       b       Block special device file
-#       p       Fifo (named pipe)
-# uid is the user id for the target file, gid is the group id for the
-# target file.  The rest of the entries (major, minor, etc) apply only 
-# to device special files.
