mbedtls/tests/suites/test_suite_ecp.function
Paul Bakker dbd443dca6 Adapted .function files and .data files to new test framework 
Changes include:
 - Integers marked with '#' in the .function files.
 - Strings should have "" in .data files.
 - String comparison instead of preprocessor-like replace for e.g. '=='
 - Params and variables cannot have the same name in .function files
