From dc890c2dcd63a90de68ee5f0253eefbb89d725f0 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sun, 7 Jun 2009 23:27:31 +0100 Subject: [ARM] 5544/1: Trust PrimeCell resource sizes I found the PrimeCell/AMBA Bus drivers distrusting the resource passed in as part of the struct amba_device abstraction. This patch removes all hard coded resource sizes found in the PrimeCell drivers and move the responsibility of this definition back to the platform/board device definition, which already exist and appear to be correct for all in-tree users of these drivers. We do this using the resource_size() inline function which was also replicated in the only driver using the resource size, so that has been changed too. The KMI_SIZE was left in kmi.h in case someone likes it. Test-compiled against Versatile and Integrator defconfigs, seems to work but I don't posess these boards and cannot test them.
