Add a set of test cases for cs_amp_set_efi_calibration_data(). Broadly there are two type of behavior being tested: How the EFI is updated: - Create a new EFI - Overwrite part of existing content - Overwrite part of zero-filled preallocated content - Grow the file to append new content And how the location within the content is chosen: - Overwrite a specific array entry - Overwrite an entry with the same calTarget (silicon ID) - Overwrite a free entry - Append after existing data Plus some cases for error conditions.
