kareem f4218ddde9 reharden!: gpio_control_block 
- reimplement using a sparecell
- reimplement using newest open_pdks

!important using openlane pre odb with some local patches which
most if not all are merged in the current head of openlane however
still takes effort to update the interactive script to be latest
openlane compatible

!important override abstract lef generated by openlane. openlane
 generates lef and mag that contain def BLOCKAGE layers that cause
congestions during top level routing

kareem 285ef6b642 reharden!: caravel 
~ update the following views:
def
mag
verilog
spef(all corners)
+ add the ability to override the interactive script filename
+ add the ability to run openlane regression using regression.config
file
~ change GRT ADJUSTMENT values
~ change pointers to some files for workarounds

!important the interactive script still needs updates
!important this was done using old openlane v0.22 and its matching
pdk
!important known workarounds:
- a custom techlef is used where large metal spacing rules are the
only ones present to avoid violations by the router
- some odd behaviour happening when a macro has a lef view
with a non zero origin. so the power routing cell is (temporarily)
modified to have a zero origin and its placement has been shifted
which doesn't match the power routing mag.
- the old openlane doesn't generate multi spef corners. they
are generated using timing-scripts repo

Effectively reverted the change to add spare logic blocks near each (#157) 
* Effectively reverted the change to add spare logic blocks near each
of the GPIO control blocks by changing the definition of
NUM_SPARE_BLOCKS to 4 (the original number of spare logic blocks)
for both caravel and caravan top level RTL verilog modules.

* Apply automatic changes to Manifest and README.rst

verification testbenches could be run from caravel referencing
caravel_mgmt_soc_litex instead of the other way around.  This file
has been reverted back to its original form.

usefully synthesizable.

Tim Edwards f5a9d4677e Revert "Implemented fix from early issue #16. Finally decided to pull the" 
This reverts commit 577cc12fe0.

Reverting the change from issue #16.  After some discussion, it has
been decided that it is up to the user to implement the pull-up and
pull-down modes correctly by setting the output enable and driving
the output to the appropriate value.  Note that this should be well
documented, if by nothing else than a validation testbench that
excercises a user pull-up and pull-down input mode.
