65 Update platform headers and add cache control commands

Cache control is currently no-ops on Potato.

64 Add display enable support for the 7-seg module skordal 3240d 20h /
63 Upgrade makefiles for use with the upgraded toolchain skordal 3243d 20h /
62 Add a couple of missing signals to a sensitivity list skordal 3271d 21h /
61 Add 7-segment display controller to the Potato SoC skordal 3273d 01h /
60 Remove out-of-date comment skordal 3286d 17h /
59 Remove branch: "new-privileged-isa" skordal 3306d 18h /
58 Merge branch new-privileged-isa (r48-r57) into trunk

This adds support for the newly published supervisor extensions
version 1.7. In addition, a processor datasheet has been added
and the timer_clk signal has been properly connected in the
example design and the SoC testbench.

46 Remove branch: cache-playground skordal 3338d 16h /
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 3338d 16h /
44 Add instruction cache and use the WB adapter as dmem interface skordal 3338d 16h /
43 Improve instruction fetch logic skordal 3338d 16h /
42 Move check for stall from irq_asserted to exception_taken in EX stage skordal 3338d 16h /
41 Make continouous status register reads asynchronous skordal 3338d 16h /
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.
