Tim Edwards 42805f767e Removed some references to mgmt_soc_litex files that had been added 
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.

Tim Edwards e2556cc11b Removed the SPARE_LOGIC_BLOCK ifdef...endif from around the spare 
logic in caravel.v and caravan.v.  These had been added to the
caravel_stanford branch because the spare logic blocks are not
usefully synthesizable.

Tim Edwards 72341326e2 Corrected a typo in the definition of the mgmt_io_oeb vector in 
caravel.v, which should be the same as mgmt_io_in and mgmt_io_out
and should equal the number of user I/O pads (38).

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.

Tim Edwards 577cc12fe0 Implemented fix from early issue #16. Finally decided to pull the 
trigger on this one in the hopes that it helps prevent user error
in implementing input pull-up and pull-down on GPIO pins.

Tim Edwards 7276623d3c Corrected the pull-up definition and revised the CSB definition to 
match the corrected defintions (namely, pull-up is configuration
0x0801, and pull-down is configuration 0x0c01).

Tim Edwards de9605a01b Modified the mgmt_protect module to change the tristate outputs to 
zero level outputs when the user project area is powered down.
That allows the synthesis tools to buffer these outputs.  The
protection from floating inputs is left as-is, but all logic that
was unnecessary to be specified by gate instances has been changed
to RTL.  This leaves only a handful of signals (logic analyzer input,
user IRQ, and wishbone data out and acknowledge out) to be handled
by explicit logic gate instances.
