xz gives *much* faster decompression times for the SDK which in itself is a good reason to use it. It also gives better compression. One downside is its slower but we care about the end user case first, build performance secondary. It also assumes the SDK user has a tar capable of understanding a xz compressed file but that should be common enough now. Signed-off-by: Richard Purdie <redacted>
