commit 73387f989c87b7b62e8410acc29499bf6c285f74 Author: Julius Werner jwerner@chromium.org Date: Wed Aug 28 14:43:14 2013 -0700
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.
