In my opinion, you should get Thomas Koeller's patch for that at91 hal
and apply that first.  This will rearrange the hal/arm/at91 subdirectory
with a var/ (common) and eb40/ subdirectories.  Then apply my patch
which corrects a couple small issues with Thomas' patch and creates
an eb40a/ subdirectory.  Then look at the eb40/ and eb40a/ ports and
determine how they vary from the eb63.  Make the appropriate
changes (memory layout, chip selects, clock speed) to the source
files.  Then update ecos.db and copy/paste the eb40 sections for the
eb55.

For those wanting to port the eb55, you can do the same thing.  The
whole process should take only a couple hours.

Patches can be found in the ecos-patches mailing list archive.  See
