Properties / Entry arguments:
- pattern: Filename pattern to match the files to include
- compress: Compression algorithm to use:
none: No compression
lz4: Use lz4 compression (via 'lz4' command-line utility)
This entry reads a number of files and places each in a separate sub-entry
within this entry. To access these you need to enable device-tree updates
at run-time so you can obtain the file positions.
