Wow. The newest version of Vivado does not like the enums as parameters.
...
The solution is simple. I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

Modified bootloader to access GUID partitions. SDC interrupt to PLIC.
...
Since writing an SD card image generation script, the bootloader
needed to be altered to access individual binaries from specific
partitions. A new file, gpt.c with it's header gpt.h, have been added
to the bootloader to facilitate this.
The SDC has been added to the device tree for the VCU108
board. Additionally the SDC interrupt signal was added to the PLIC
node in the device tree. The PLIC itself was modified to accept the
SDC interrupt signal.

Vivado requires an intermediate wrapper file for parameterization.

FPGA synthesis is broken. This commit moves closer to fixing the issues causes by parameterization.

Found the first issue. the axi clock converter was stuck in reset because the polarity was reversed.

Improved constraints and set ddr3 voltage to correct 1.35V. This voltage is only for synthesis. However I'm concerned because the gui did not let me select 1.35V.

Finally we are building the fpga and can view the ila. we are getting out of reset, but we are stuck at PCM = 10b8.

Dang. Looks like the reset button on the arty a7 is actually resetn. I wish they'd named it that way.

Yay! We now have a functional ila and the uart connection on the pc side works. However the CPU is stuck in reset. Not really sure what's going on there.

Found and fixed the major architecture issue with the mig 7 used in the arty a7 board.
...
mig 7 is completely different from the ddr4 mig in that the internal pll does not general the required clocks. An external mmcm is required to general two inputs clocks and the required user clock.

First the xci files already include the xdc constraints for each IP block. There is no need to include the xdc files explicitly.
Second the bidir buffer for the sd card was connected backwards.
