b756b248b4 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.

b3aaa87cba 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.
