--- Comment #2 from Alex Deucher alexdeucher@gmail.com --- Yes, this is intended. The new firmware uses a new header format with version information in the header so we can update that version seemlessly without needing a add driver support for a new firmware file. The upper case firmware is the old version for kernels without explicit support for the new firmware.
