test: check if there is a change in the simulation output
io: Revise handling of memory mapping, update memory map, refactoring of timer device in simulator.
io: Update I/O device addresses in test cases.
Merge branch 'master' of github.com:t-crest/patmos
simulator: Include <climits> in dbgstack.cc for definition of INT_MAX.
mcache: fixed bug after call/ret restart
changed absolut addresses to relative addresses
Merge branch 'master' of github.com:t-crest/patmos
test: Recompile simulator test 24.
chisel: Fixes in fetch stage.
chisel: Use same addressing modes for call and brcf in the hardware.
chisel: Fix computations for stalling, minor cleanups.
doc: Comments on upcoming ISA revision.
chisel: Cleanups in emulator code.
simulator: Make interrupt instruction enter debugging and profiling frames.
Cleanup of binary loading, added check tool.

* Cleanup ELF and binary loading, make padasm handle ELF
* Added pacheck tool to statically check for common errors in the binary
* Fixed delay slot handling for interrupts
pasim: Fix reading from redirected UART
pasim: use s10 to store function offset at interrupt, store function base instead of PC in s9
pasim: refactoring of instruction caches

* Introduced LRU instruction cache
* Load interrupt handlers from method cache
* Added options to set burst size and block size of memories
pasim: Align memory requests to burst size
