Subject: [PATCH 4/4] sandbox: allow "make ARCH=sandbox allyesconfig"
Date: Thu, 26 Jun 2014 10:49:17 +0200	[thread overview]
Message-ID: <1403772557-28482-5-git-send-email-holgerschurig@gmail.com> (raw)

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.

This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.
