* - update caravan configuration
* change correct gpio_default blocks instance names
* implement powerrouting work around
* place spare logic blocks
* keep the history of runs and sym link last/final one
* - update caravan mag, def and gl views
- add fake power routing cell in the rtl as a placeholder for openlane
to prevent routing on that cell
- fix some syntax errors in chip_io_alt
- match simple_por lef pins with mag by regenerating it
* Apply automatic changes to Manifest and README.rst
* add caravan power routing lef
* - update mag and def view of caravan
- add_macro_placement for fake cell
* Added back the power routing to Caravan, fixed DRC errors, ran LVS,
corrected placement of isolated substrate regions, and replaced the
signal routing for the analog lines. Be aware that merging with
main may cause issues with the mgmt_protect.mag file and its
subcells mprj2_logic_high.mag and mprj_logic_high.mag. It may be
worth cherry-picking the files to merge and exclude those layouts.

* - add openlane patch file to for input buffering workaround
- update configuration of mgmt protect
* mgmt_protect updated
* mgmt_protect updated
* remove some via3 to fix power shorts

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.

chip's GDS is generated with "cif *hier write disable", the POR
will continue to have the GDS with the proper hierarchical processing.
verilog for both caravel and caravan. Hand-edited the RTL and GL netlists to
correct this; still need to correct the layouts. The error causes the user1
side clock, load, and reset buffers to drive the user2 side as well as the user1
side, making a huge mess of the routing. Will route this by hand.
got removed from its net by a chang in the LEF view of an I/O pad, and
a lack of declaration of an array to attach to pwr_ctrl_out in the
verilog, which is valid verilog but netgen can't know the bus size
without the no-connect net being declared. The remaining issue has to
do with separation of ground domains in the mgmt_protect block.
an unconnected wishbone bus (unconnected inputs). Added the missing
signals for the user IRQ enables to management protect (which have
to come from the management SoC).
