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.

Created full FPGC6 verilog simulation, added Quartus code from FPGC5 with CPU from FPGC6. Works in hardware, but has combination loop somewhere at the arbiter and the registerbank and stack are not using block ram

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
