includes RTL change inside the padframe definition to remove one
previously unnoticed hard-wired connection between VDDIO and a
3.3V domain digital input pin.
* 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

- rtl updated
~ add one column to the right to pass placement congestion
~ density adjusted (probably has no effect)
+ manually add isosubstrate layer in mag and gds from older iterations
!important still need to run dynamic simulations
!important depends on some updates to openlane
!important need to be able to recreate using newer openlane versions
* Added enough spare logic blocks to have the existing four above
the processor, plus one each per GPIO (38 for caravel, 27 for
caravan).

* Removed the SRAM read-only interface by wrapping all related code
in an ifdef for "USE_SRAM_RO_INTERFACE", which is undefined.

to caravel_netlists.v when attempting to determine if the
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.
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.
