51	Add scall/ecall, sbreak/ebreak and timer interrupt tests	skordal	3285d 05h	/potato/
50	Update test environment to the new supervisor ISA	skordal	3297d 05h	/potato/
49	Correct spelling of "privileged"	skordal	3307d 04h	/potato/
48	Create branch for upgrading to the new privileged ISA	skordal	3307d 04h	/potato/
47	Tag version 0.1 of the Potato Processor	skordal	3307d 12h	/potato/
46	Remove branch: cache-playground	skordal	3310d 06h	/potato/
45	Merge branch cache-playground (r23-r30 and r34-r44) into trunk This primarily adds the following features the the processor: - A direct-mapped instruction cache with configurable cache line width and number of cache lines. - Various bug fixes for bugs that appeared when the processor could run instructions at full speed but had to stall for data. - A "Hello World" test application.	skordal	3310d 06h	/potato/
44	Add instruction cache and use the WB adapter as dmem interface	skordal	3310d 07h	/potato/
43	Improve instruction fetch logic	skordal	3310d 07h	/potato/
42	Move check for stall from irq_asserted to exception_taken in EX stage	skordal	3310d 07h	/potato/
41	Make continouous status register reads asynchronous	skordal	3310d 07h	/potato/
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.	skordal	3310d 07h	/potato/
39	Disable IRQs when handling exceptions	skordal	3310d 07h	/potato/
38	Add "Hello World" test application	skordal	3310d 08h	/potato/
37	Add macro to set the TOHOST register from C code	skordal	3310d 08h	/potato/
36	Ensure correct read of CSR after stall	skordal	3310d 08h	/potato/
35	Prevent jumping/branching when stalling	skordal	3310d 08h	/potato/
34	Prevent flushing the pipeline if it is stalling	skordal	3310d 08h	/potato/
33	Ensure correct read of CSR after stall	skordal	3310d 08h	/potato/
32	Prevent jumping/branching when stalling	skordal	3313d 05h	/potato/
31	Prevent flushing the pipeline if it is stalling	skordal	3313d 06h	/potato/
30	Add testcase for a combination of instructions that fail when using cache	skordal	3315d 11h	/potato/
29	Add reset functionality for the WB arbiter state machine	skordal	3318d 06h	/potato/
28	Add rudimentary User's manual	skordal	3324d 05h	/potato/
27	Prevent exceptions from being taken while stalling	skordal	3324d 07h	/potato/
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	3324d 10h	/potato/
25	Add placeholder cache modules and a wishbone arbiter	skordal	3326d 15h	/potato/
24	Remove unused STRINGIFY macros	skordal	3327d 04h	/potato/
23	Create branch to use for implementing a cache	skordal	3327d 04h	/potato/
22	Fix the potato_get_badvaddr() macro	skordal	3327d 04h	/potato/
