Subject: [PATCH 6/6] fs: squashfs: Enable squashfs XZ support when XZ is enabled
Date: Mon, 24 Oct 2016 08:28:43 +0200 [thread overview]
Message-ID: <20161024062843.2796-7-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20161024062843.2796-1-s.hauer@pengutronix.de>
XZ support itself is much more expensive than the squashfs XZ wrapper,
so it makes sense to just compile XZ support into barebox when XZ
support is available. No need to ask the user for it.

- Saying Y here includes support for reading Squashfs file systems
- compressed with XZ compression. XZ gives better compression than
- the default zlib compression, at the expense of greater CPU and
- memory overhead.

- XZ is not the standard compression used in Squashfs and so most
- file systems will be readable without selecting this option.
