R. Timothy Edwards 30d35947f1
Added decap cells to the gate-level verilog for the (#343)
gpio_signal_buffering_alt cell (caravan chip).  This was
previously done for gpio_signal_buffering (caravel chip) but
the same thing had not previously been done for caravan.

Fixes to caravan for LVS and ERC (#330)
* Corrected missing part of porb_h route in the caravan chip_io_alt
layout.  Correcting the indexing of the "mprj_io_one" connections
to "mgmt_io_oeb" on the left-hand side of caravan, as they were
connecting back to the right side and making a mess of wiring,
instead of being wired locally directly to the nearest I/O.

* Apply automatic changes to Manifest and README.rst

* Corrected the unconnected mgmt_io_in inputs to housekeeping on
the caravan chip (which correspond to the GPIOs that do not exist
in caravan) by connecting them to the "zero" outputs of the
closest GPIO control blocks.

* Apply automatic changes to Manifest and README.rst

update caravel with tying `porb_h_in` with `por_l_in` (#326)
* update caravel with tying `porb_h_in` with `por_l_in` at the `mgmt_core_wrapper` in the top-level layout:
- `porb_h_in` shouldn't be left floating as it is an input to `clkbuf_16`

* add caravel-eco.gds (same as caravel.gds)

Syntax changes that are non-functional from a synthesis perspective. (#324)
* Syntax changes that are non-functional from a synthesis perspective.
There are a few errors that are caught by commercial tools and halt
synthesis, which are handled more gracefully by the open source
tool flow.  In housekeeping.v:  Some wires declared after they are
used.  In housekeeping_spi.v:  A non-blocking "=" assignment used
where a blocking "<-" assignment was intended.
