Tim Edwards e2ee74c591 Changed "simple_por" in both caravel and caravan to be an abstract
view pointing to the contents of ../gds/ so that when the assembled
chip's GDS is generated with "cif *hier write disable", the POR
will continue to have the GDS with the proper hierarchical processing.

Tim Edwards be98da0fe6 Added spare logic block to caravel layout and verilog GL, wired
it to the power supply, and checked top-level LVS.

Tim Edwards 08a2c90940 Made updates to correct LVS errors in caravan. Found one major error in the RTL
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.

Tim Edwards 515b5a54f2 Updates for LVS. Only LVS issue remaining for caravel is how to get the
ground domains to extract independently.

Tim Edwards 6eb8bb54de Several more LVS corrections, including fixing a label in chip_io that
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.

Tim Edwards a7148378a0 Added as many of the magic database layout files as are expected to remain
unchanged between the caravel and caravel_openframe repositories.
