42 Move check for stall from irq_asserted to exception_taken in EX stage skordal 3674d 03h /
41 Make continouous status register reads asynchronous skordal 3674d 03h /
40 Reduce example design clock frequency to 50 MHz

- Also includes a minor change to make the address decoder/interconnect work
better with burst transfers.

33 Ensure correct read of CSR after stall skordal 3674d 04h /
32 Prevent jumping/branching when stalling skordal 3677d 01h /
31 Prevent flushing the pipeline if it is stalling skordal 3677d 02h /
30 Add testcase for a combination of instructions that fail when using cache skordal 3679d 07h /
29 Add reset functionality for the WB arbiter state machine skordal 3682d 02h /
28 Add rudimentary User's manual skordal 3688d 01h /
27 Prevent exceptions from being taken while stalling skordal 3688d 03h /
26 Prevent exceptions from being taken while stalling

Jumping to an exception handler while stalling and waiting for a load/store
instruction to finish can cause undefined results from the load/store
instruction. This actually fixes the issue mentioned in revision r20.
skordal 3688d 06h /
25 Add placeholder cache modules and a wishbone arbiter skordal 3690d 11h /
24 Remove unused STRINGIFY macros skordal 3691d 00h /
23 Create branch to use for implementing a cache skordal 3691d 00h /
22 Fix the potato_get_badvaddr() macro skordal 3691d 00h /
21 Upgrade the example design to use a 60 MHz system clock skordal 3691d 01h /
20 Fix SHA256 benchmark crash by storing all registers on exception handler entry

This problem will disappear when the processor is updated to conform to the
new supervisor specification, which will allow us to use a compiler that
conforms to the new "official" ABI.
skordal 3691d 01h /
19 SHA256 benchmark: allow compiler to inline at will skordal 3691d 01h /
18 instr_misalign_check: add do_jump to sensitivity list skordal 3693d 01h /
17 Improve detection of unaligned instructions skordal 3697d 08h /
16 Correct grammar in source code comment skordal 3697d 08h /
15 SHA256 benchmark: fix Makefile syntax error skordal 3704d 01h /
