44 Add instruction cache and use the WB adapter as dmem interface skordal 3312d 12h /
43 Improve instruction fetch logic skordal 3312d 12h /
42 Move check for stall from irq_asserted to exception_taken in EX stage skordal 3312d 12h /
41 Make continouous status register reads asynchronous skordal 3312d 12h /
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.

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 3326d 15h /
25 Add placeholder cache modules and a wishbone arbiter skordal 3328d 20h /
24 Remove unused STRINGIFY macros skordal 3329d 09h /
23 Create branch to use for implementing a cache skordal 3329d 09h /
22 Fix the potato_get_badvaddr() macro skordal 3329d 09h /
21 Upgrade the example design to use a 60 MHz system clock skordal 3329d 10h /
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.

19 SHA256 benchmark: allow compiler to inline at will skordal 3329d 10h /
