Interesting thread, very informative, starting at
http://lists.debian.org/debian-arm/2012/03/msg00002.html.

The Raspbery Pi uses an ARMv6 processor running in little-endian
mode (ARM supports both big-endian and little-endian modes) with
hardware floating point.  This is quite a unique combination;
processors with hardware floating point are usually ARMv7; the
armhf port of Debian requires ARMv7.

Debian armel works on the Raspberry Pi but does not take advantage
of the floating point hardware.  Note that if you're going to
program in Ada on such a machine, you might find that 256 MiB
of RAM is very limited. You probably don't want gnat-gps or emacs
as your IDE on such a machine.
