Assembler only needs Int: function, fixed position of program lenght. Ported ROM and UART bootloader over from FPGC5. Updated documentation on interrupts. Added resets. Fixed bug in MU. Increased stack size. Tested everything in hardware. Probably some other fixes and things I forgot.

Regbank and stack are now placed in BRAM, fixed combinational loop but further testing needed.

Added DataMem to MU via Arbiter, fixed several bugs while doing this. Works with test code, but will most likely still contain bugs in certain cases.

Found bug where the next instruction after READ/WRITE is skipped if DataDelay but no InstrDelay

Basic CPU design now done with afaik working hazard detection, forwarding and stalls. Tested in hardware on a EP4CE6 using two SSDisplays and dip switches to view the register content (and see if it matches the simulation). No interrupts yet as this can probably be done at a later stage.

Jump flush now seems to work. Made simple Quartus project to test in hardware and it seems to work fine there as well

Started working on the CPU pipeline. Basic load, arith and jumps seem to work now. No hazard handling yet.
