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 33ca4e11ef Additional corrections, mostly to the housekeeping module. The 
top-level simulation now passes the GPIO testbench.

Tim Edwards 1863a7c529 A number of small corrections. 2021-10-16 23:55:57 -04:00
Tim Edwards 2f74fa83ee Reinstated the logic analyzer as a standard interface for the 
management SoC.

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

Tim Edwards 332f9ec2e7 Seeding with documentation of pinout and verilog RTL (mostly unchanged 
from original except to remove blocks that are not supposed to be in
this repository like the processor core and the storage).
