48 Create branch for upgrading to the new privileged ISA skordal 3289d 00h /potato/
47 Tag version 0.1 of the Potato Processor skordal 3289d 08h /potato/
46 Remove branch: cache-playground skordal 3292d 02h /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 3292d 02h /potato/
44 Add instruction cache and use the WB adapter as dmem interface skordal 3292d 02h /potato/
43 Improve instruction fetch logic skordal 3292d 02h /potato/
42 Move check for stall from irq_asserted to exception_taken in EX stage skordal 3292d 02h /potato/
41 Make continouous status register reads asynchronous skordal 3292d 02h /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.
