* ARM: boot: Add an implementation of strnlen for libfdtRob Herring2016-02-111-0/+9
| | | | | | | | Recent versions of libfdt add a dependency on strnlen. Copy the implementation in lib/string.c here, so we can update libfdt. Acked-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Rob Herring <robh@kernel.org>
* ARM: zImage: gather some string functions into string.cNicolas Pitre2011-09-141-0/+127
This is a small subset of string functions needed by commits to come. Except for memcpy() which is unchanged from its original location, their implementation is meant to be small, and -Os is enforced to prevent gcc from doing pointless loop unrolling.
