+ * @file rsp2elf.s
+ *
+ * This file converts binaries output from armips into a suitable elf file to be linked into the project.
+ * It requires the following preprocessor definitions to be provided when assembled:
+ *  UC_NAME          : The microcode name, used to generate symbol names for text and data
+ *  UC_TEXT_SECTION  : The program section to place the microcode text into, usually .text
+ *  UC_DATA_SECTION  : The program section to place the microcode data into, usually .rodata
+ *  UC_TEXT_BIN_PATH : The path to the microcode text binary
+ *  UC_DATA_BIN_PATH : The path to the microcode data binary
