Leon Alrae 55e9409366 softmmu: provide softmmu access type enum
New MIPS features depend on the access type and enum is more convenient than
using the numbers directly.

Alexander Graf 582b55a96a roms: Flush icache when writing roms to guest memory
We use the rom infrastructure to write firmware and/or initial kernel
blobs into guest address space. So we're basically emulating the cache
off phase on very early system bootup.

That phase is usually responsible for clearing the instruction cache for
anything it writes into cachable memory, to ensure that after reboot we
don't happen to execute stale bits from the instruction cache.

So we need to invalidate the icache every time we write a rom into guest
address space. We do not need to do this for every DMA since the guest
expects it has to flush the icache manually in that case.

This fixes random reboot issues on e5500 (booke ppc) for me.

Paolo Bonzini 7443b43758 exec: move qemu_ram_addr_from_host_nofail to cputlb.c
After the next patch it would not be used elsewhere anyway.  Also,
the _nofail and the standard versions of this function return different
things, which is confusing.  Removing the function from the public headers
limits the confusion.

Andreas Färber ce927ed9e4 hwaddr: Make hwaddr type usable beyond softmmu
While not normally needed for *-user, it can safely be used there since
always based on uint64_t, to avoid ifdeffery.

To avoid accidental uses, move the guards from exec/hwaddr.h to its
inclusion sites.  No need for them in include/hw/.

Prepares for hwaddr use in qom/cpu.h.

There is no reason to avoid a recompile before accessing unassigned

Paolo Bonzini 2a8e749909 exec: eliminate io_mem_ram
It is never used, the IOTLB always goes through io_mem_notdirty.

In fact in softmmu_template.h, if it were, QEMU would crash just
below the tests, as soon as io_mem_read/write dispatches to
error_mem_read/write.
