[ydl-gen] Programming the CELL BE on YDL 5

[Jonathan Bartlett]

I got the 64-bit libspe working just fine.  I don't know for sure if it 
works with full 64-bit addresses, but I was able to compile, link, and 
run against it just fine.  I just did "rpmbuild -bb --target 64 
libspe.spec".  Doing that also gave me the RPM for elfspe, which allows 
you to run SPE programs directly through binfmt_misc.

As for the /proc entries, on IBM's system simulator, there is a whole 
directory for each SPE in /proc/device-tree/cpus/PowerPC,BE at 0/spes with 
each directory having the following files:
  - device_type
  - isrc
  - linux,phandle
  - local-store
  - name
  - priv1
  - priv2
  - problem
  - reg
  - unit-id

The device tree on the PS3 doesn't have any /proc entries that I could 
find for the SPEs.  I had originally thought that these were required to 
do things such as talk to SPE mailboxes, but further experimentation 
proved that mailbox communication with libspe worked just fine without them.
