From: Arnd Bergmann Date: Tue, 24 Apr 2012 15:51:47 +0000 (+0000) Subject: ARM: bcmring: remove include/csp/ subdir X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8a3fb8607a48ed74db3aaa87d8af7febcaa5d814;p=deliverable%2Flinux.git ARM: bcmring: remove include/csp/ subdir The csp/*.h headers get into the way of multiplatform kernels and are generally not needed anyway. This removes the ones that are completely free of content and moves the other ones to mach/csp/, which already holds a bunch of these.
