4c0d039076
This patch reworks type usage in generic code, drivers and ARM platform files to make it more portable. The major changes done with respect to type usage are as listed below: * Use uintptr_t for storing address instead of uint64_t or unsigned long. * Review usage of unsigned long as it can no longer be assumed to be 64 bit. * Use u_register_t for register values whose width varies depending on whether AArch64 or AArch32. * Use generic C types where-ever possible. In addition to the above changes, this patch also modifies format specifiers in print invocations so that they are AArch64/AArch32 agnostic. Only files related to upcoming feature development have been reworked. Change-Id: I9f8c78347c5a52ba7027ff389791f1dad63ee5f8
