With my most recent automake patch (automake II) we could even simplify more
files below make/, because the host-compiler related parts of those files
aren't used anymore :-.
Whatsoever, the patch below should fix this problem.
Note: This is a mere bug fix, it doesn't move any of the variables involved
to target.cfg nor does it try to eliminate any variable.

fix some problems encountered when reusing this driver on
a SPARC ERC32 based Tharsys board. He eliminted the need
for TX interrupts and added code that can optionally ensure that
the IP address is 32-bit aligned. He also fixed a handful of
problems that only occured because the 8 Mhz ERC32 was
enough slower than the 100 Mhz PPC603e that timing
issues in this driver were magnified.

This patch is the most scary of all proposals I've been mailing to you
this week until now.
It consists of 3 parts:
1. a patch
2. a perl script (acpolish)
3. a shell script wrapper to invoke the perl-script.
The perl-script reads in each Makefile.in and modifies them
("polishes/beautifies" them :-).
These modifications are not easy to describe:
Basically, it hard-codes some automake Makefile-variables and rules into
RTEMS autoconf-Makefile.ins (Note: autoconf vs. automake!!) and converts
some settings/variables to configure scripts' requirements (Yes,
plural).
E.g. it adds the automake standard variables $top_builddir and $subdir,
adds dependency rules for automatic re-generation of Makefiles from
Makefile.in, adds support variables for relative paths to multiple
configure scripts etc.
The patch is a one-line patch to enable the support of the new features
added by acpolish.
The shell script is a wrapper which pokes around inside of the source
tree for Makefile.ins and invokes acpolish on all autoconf-Makefile.ins.
acpolish is designed to be able to run several times on the same
Makefile.in and may once become a more general tool to convert RTEMS
Makefile.in to automake. Therefore, I'd like to keep it inside of source
tree. (e.g. as contrib/acpolish or c/update-tools/acpolish). However, it
doesn't make sense to export it outside of RTEMS.
To apply this:
cd <source-tree>
patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff
tar xzvf <path-to>/rtems-rc-polish.tar.gz
./rtems-polish.sh
./autogen
Note: The path contrib/acpolish is hard-coded into rtems-polish.sh, if
you decide to put it in an alternative place, please modify
rtems-polish.sh to reflect this change.
Later:
cvs rm make/rtems.cfg (It isn't used anymore)
cvs add contrib
cvs add contrib/acpolish
cvs commit
I've tested this intensively, but naturally I can't exclude bugs.
Ralf.
PS.: Most probably, this is the last "Towards automake" patch. The next
one probably will be a real automake patch.

portion is now in the libchip tree and the dmv177 configuration is in
the dmv177 bsp. The performance impact of libchip'ing this driver
was minimal.
