mkcramfs changes to switch endianness

I'm getting ready to try using cramfs in the 2.4.4 kernel.
Anybody done the work to make 'mkcramfs' create a big-endian
image on a little-endian PC?   Before I reinvent the wheel,
I'd like to find out if anybody as done it (and would like
to share   :)

cramfs is still endian dependant.  Linus has a couple solutions to this
problem, but last time I checked he wasn't clear which was the best.  go
for it and let us know how it turns out.

I have the changes for the pre-midori mkcramfs.  works fine but it
is very ugly because of the use of bit fields.  Have been running it for
a few months and it does work fine :)  We are in the process of
integrating the latest changes from transmeta, but here is the patch for
the old version.

THANKS for the patch!

Just out of curiousity, where do you get the source for the transmeta
changes (their Midora Linux, I assume....).  I went looking at their
web site, and the FTP location they pointed to contained a
midora-1.0.0-beta1*.tar.gz file that was only 36K.....where's the real
thing?

We used this, as a starting point (or one of the other references to
this patch, i just did a google search to find it again).

I was hoping that it was all on sourceforge, but I guess not.  We should
finish integrating the endianness changes against this patch pretty
soon.  Maybe if someone else knows if there is a more up to date version
around they could let us know.

that file is just the build structure/files.  once you install that you
need to download the rest from the apps dir on the ftp site.  start at
http://midori.sourceforge.net.

That is the patch include with midori.  If i remember correctly, it is
included in the kernel mlz. mlz is the midori packaging method,
basically a tar gz file.

it is all there on sourceforge, just need to dig a little:)
