Tim Edwards 184f4a637c Added the rest of the testbenches: mprj_bitbang, perf, pll, qspi, and
storage.  Not all of these pass simulation checks.  Added back the
bit-bang control of the GPIO programming.  Added back the read-only
interface between the housekeeping module and the SRAM 2nd port.
Revised the memory map text document to reflect the addition of the
SRAM ports.  There is not yet a testbench for the SRAM read-only
interface.

Tim Edwards 767342e183 Added a completely revised sysctrl testbench based on accessing the
housekeeping SPI through the back-door wishbone interface.  Checks
most of the SPI registers (but could do more).

Tim Edwards 2e57b5da08 Added and debugged two more testbenches, gpio_mgmt and hkspi. 2021-10-18 11:25:26 -04:00
Tim Edwards 842200b7ec Changed the memory map to move the 2e and 2f wishbone domains into
the 26 domain (now dedicated to the housekeeping module), with
2e0... now 261... and 2f0... now 262...  Although this is not
strictly backwards-compatible, the addresses in defs.h have been
modified so that C code remains valid with a recompile.

Tim Edwards bdfa747145 First major update; current code passes syntax checks in iverilog
and simulates, but fails testbench (not surprising at this stage).
