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.
