- added memory access functions and tests to worker cpu
- not yet tested on actual hardware, because of program download problems...
- little bug fixes to code
- better monitoring

- still not working....
- added debug port to fsl2fifo adapter
- minor changes
- finally found bug: reconos' memory subsystem accepts only request with up to 256 Bytes.
- memory read does work now, memory write still has to be adapted.
- achieved read speed:  56000 Bytes in 7 ms : approx. 7 MB/s
-  restructured main() a lot
- fixed bugs
- working: any number of threads on host and hardware threads
- needs testing: workercpus and shadowing
- fixed error in host implementation of RQUEUE sorter
- fixed Reconos Queue Implementation again: accidently changed the interface to it, so that the Hardware implementation didn't work.
- compilation for microblaze shall be default
- added workercpu implementation to sort_rq
- changes from master branch
- shadowing mode do work now
- cleaned up main() a bit more
Merge branch 'workercpu' into shadowing

- additionally bug fixed workercpu mem_read and mem_write functions
- implemented workercpu program for shmem interface
	- Warning: shmem works only with disabled data caches!

- ignoring *.elf.size files, which are geenrated by the XSDK
- added first version of:
 - plb2hwif bus adapter: grants access to hardware interface of modules in the reconos system
 - sort_demo with HWIF support
 - software to access the hwif registers

- System is not functional at the moment and needs debugging
- working command line tool for accessing performance monitors in hw threads
- changed static hwt identification array  in sort_demo.c to test new hwif interface
- static hwt identification will be soon replaced by autoconfiguration via HWIF
- latest updates to the hwif interface
- with this commit, hwif is considered working!
- added 3 applications from the Mibench Hybrid Bachelor Thesis by Alexander Sprenger.
- they need to be adapted to the current Reconos version and enhanced with shadowing
- merged matrixmul from master branch
- may still not be the most recent matrixmul, as my master copy is quite old
