The cpu_physical_memory API is legacy (see commit b7ecba0f6f6):
``cpu_physical_memory_*``
~~~~~~~~~~~~~~~~~~~~~~~~~
These are convenience functions which are identical to
``address_space_*`` but operate specifically on the system address space,
always pass a ``MEMTXATTRS_UNSPECIFIED`` set of memory attributes and
ignore whether the memory transaction succeeded or failed.
For new code they are better avoided:
...
This series removes:
- cpu_physical_memory_is_io()
- cpu_physical_memory_rw()
and start converting some
- cpu_physical_memory_map()
- cpu_physical_memory_unmap()
calls.

"system/memory: Split address_space_write_rom_internal"
Philippe Mathieu-Daudé (15):
docs/devel/loads-stores: Stop mentioning
cpu_physical_memory_write_rom()
system/memory: Factor address_space_memory_is_io() out
target/i386/arch_memory_mapping: Use address_space_memory_is_io()
hw/s390x/sclp: Use address_space_memory_is_io() in sclp_service_call()
system/physmem: Remove cpu_physical_memory_is_io()
system/physmem: Pass address space argument to
cpu_flush_icache_range()
target/s390x/mmu: Replace [cpu_physical_memory -> address_space]_rw()
target/i386/whpx: Replace legacy cpu_physical_memory_rw() call
target/i386/kvm: Replace legacy cpu_physical_memory_rw() call
target/i386/nvmm: Inline cpu_physical_memory_rw() in nvmm_mem_callback
hw/xen/hvm: Inline cpu_physical_memory_rw() in rw_phys_req_item()
system/physmem: Un-inline cpu_physical_memory_read/write()
system/physmem: Inline cpu_physical_memory_rw() and remove it
hw/virtio/vhost: Replace legacy cpu_physical_memory_*map() calls
hw/virtio/virtio: Replace legacy cpu_physical_memory_map() call
