From f09f2247d7584975d17a7d4755b279c1c3f6f001 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 28 Aug 2013 14:43:14 -0700 Subject: arm: libpayload: Make cache invalidation take pointers instead of integers This minor refactoring patch changes the signature of all limited cache invalidation functions in coreboot and libpayload from unsigned long to void * for the address argument, since that's really what you have in 95% of the cases and I think it's ugly to have casting boilerplate all over the place.
