Tim Edwards 2f6fe69b36 Corrected the gen_gpio_defaults.py script so that it behaves 
correctly no matter how the "gpio_defaults_block.mag" and
"gl/gpio_defaults_block.v" are defined.  Previously it assumed
that they both defined all bits as zero, which was not the case
for the layout.  Now both define bit value 0x0402 and the script
can flip bits either direction as needed in both verilog and
layout

Tim Edwards 7a45a096a5 Added a testbench that exercises the SRAM 2nd (read-only) port, as 
it was configured for the caravel_pico SoC, with the housekeeping
SPI able to access the upper 256-word section of the memory if the
CSB bit in the housekeeping control register is cleared.  This
testbench tests both access through housekeeping and access directly
from the SoC through the memory-mapped address.

Tim Edwards 1b3fe4379c Corrected the placement of the isosub layer in the layouts so that 
it is exactly overlapping;  this resolves issues with LVS.  Also:
Corrected the references to the OpenLane/ path in the .mag files
by changing them to the canonical $PDKPATH reference.

Tim Edwards 1526214cc1 Modifications to some of the Makefiles to make the specific RISC-V 
architecture type passed to gcc as the value to the '-march='
option an environment variable, setting that environment variable
to "rv32imc" by default, and overriding it with "rv32ic" specifically
for the new caravel_pico without the multiplier and divider option,
on testbenches "mem" and "storage" which both have multiplies in the
C code.

Tim Edwards 55836db2d2 Added a reference to the new file "gl/mgmt_defines.v" in the 
caravel_pico repository.  The issue is that each SoC implementation
defines its own modules and therefore needs its own includes.  The
implication is that this file now needs to exist in every SoC
implementation's verilog/gl/ directory.

Tim Edwards 28931e7968 Added more documentation, fully documenting the GPIO, and various 
aspects of the memory mapped controls for the management protection,
and the various differences between the Caravel and Caravan chips.

Tim Edwards 31e3d9c106 Started a set of text documents to describe all of the register sets 
and describe the various functions of Caravel (especially housekeeping).
This should eventually be formatted to match the rest of the
documentation.

Tim Edwards 5f563c3f4f Corrected a statement in the LVS scripts in the mag/ directory that 
is Makefile syntax, not bash syntax, and will cause the script to
produce an incorrect LVS result without generating a syntax error.

datasheet has been broken up into individual pages;  these can be recast into
sphinx or HTML as needed, while the graphics have been exported to SVG.
