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.		 skordal 3244d 12h /potato/trunk/benchmarks/
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 3276d 07h /potato/trunk/benchmarks/
24 Remove unused STRINGIFY macros skordal 3293d 04h /potato/trunk/benchmarks/
22 Fix the potato_get_badvaddr() macro skordal 3293d 05h /potato/trunk/benchmarks/
21 Upgrade the example design to use a 60 MHz system clock skordal 3293d 05h /potato/trunk/benchmarks/
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 3293d 05h /potato/trunk/benchmarks/
19 SHA256 benchmark: allow compiler to inline at will skordal 3293d 05h /potato/trunk/benchmarks/
16 Correct grammar in source code comment skordal 3299d 12h /potato/trunk/benchmarks/
15 SHA256 benchmark: fix Makefile syntax error skordal 3306d 05h /potato/trunk/benchmarks/
13 Add SHA256 benchmark code skordal 3306d 10h /potato/trunk/benchmarks/
