[PATCH 00/10] ARM: bcm: SCM and L2 cache code cleanup

From: Alex Elder
Date: Thu Apr 17 2014 - 22:31:06 EST


This series cleans up a number of things in the code that issues
secure monitor ("smc") requests for the bcm281xx and bcm21664 SoC
families. This code is currently used only for enabling the level-2
cache.

There are some bug fixes and other improvements. An assembly
language file containing a single function has been eliminated by
re-implementing the code using inline assembly. Some comments have
been expanded and clarified. Kernel configuration options allow
finer-grained control over how this code gets built. Finally, the
"kona.c" and "kona.h" files are renamed to reflect the fact that
only contain code related to level-2 cache support.

This series is based on v3.15-rc1, and depends on one patch posted
previously:
