* @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
