The core_is_buffer_*() helpers are sometimes used with physical
addresses (type paddr_t). This can cause problem on platforms where
sizeof(paddr_t) > sizeof(vaddr_t), that is on ARM32 systems with
CFG_CORE_LARGE_PHYS_ADDR=y. The FVP platform compiled for AArch32 is one
such system which as a consequence fails with:
E/TC:0 0 check_phys_mem_is_outside:335 Non-sec mem (0x880000000:0x180000000) ove
rlaps map (type 12 0xff000000:0x1000000)
E/TC:0 0 Panic at core/arch/arm/mm/core_mmu.c:336 <check_phys_mem_is_outside>
This patch fixes this problem by taking input addresses as paddr_t and
sizes as paddr_ssize_t instead. The wrapper macros which did some
automatic casting removed. The requires updates at some of the places
where these functions are called.
