Subject: [PATCH v4 07/10] arm: add a tiny kconfig configuration
Date: Thu, 31 May 2018 14:48:34 -0700	[thread overview]
Message-ID: <1527803317-31750-7-git-send-email-sstabellini@kernel.org> (raw)
In-Reply-To: <alpine.DEB.2.10.1805311447570.23991@sstabellini-ThinkPad-X260>

Add a tiny kconfig configuration. Enabled NULL and Credit schedulers.
Support only 8 cpus. It only carries non-default options (use make
olddefconfig to produce a complete .config file).

Signed-off-by: Stefano Stabellini <sstabellini@kernel.org>

---
Note that this approach has a limitation: it is not possible to "select
a range". In other words, using tiny.config NR_CPUS is set to 4. It is
not possible to increase it to 8 from config RCAR3.
