PA-RISC uses procedure descriptors. We'd need to emit a call to

Delete inline functions from tcg-target.h that don't need to be there,
move the others to tcg-target.c. Add 'Z', 'I', 'J' constraints for
0, signed 11-bit, and signed 5-bit respectively. Add GUEST_BASE support
similar to ppc64, with the value stored in a register. Add missing
registers to reg_alloc_order. Add support for 12-bit branch relocations.
Add functions for synthetic operations: addi, mtctl, dep, shd, vshd, ori,
andi, shifts, rotates, multiply, branches, setcond. Split out TLB reads
from qemu_ld and qemu_st; fix argument loading for tlb external calls.

The bug is that env->stopped is not really as comprehensive as it seems to
be (and cpu_has_work thinks); it is only valid with iothread basically,
and even then it is cleared by reset and it is not set when starting
qemu with -S.

SCBStatus is readonly, but most drivers which were derived

Historically the qemu tlb "addend" field was used for both RAM and IO accesses,
so needed to be able to hold both host addresses (unsigned long) and guest
physical addresses (target_phys_addr_t). However since the introduction of
the iotlb field it has only been used for RAM accesses.
This means we can change the type of addend to unsigned long, and remove
associated hacks in the big-endian TCG backends.
We can also remove the host dependence from target_phys_addr_t.

PowerPC CPUs have had two ways to read the time base for quite some time now.
They provide it using the mfspr instruction or - if a special bit is set in
that opcode - using mftb. For timekeeping we're currently using mftb.
While trying to get Qemu up and running on an e500v2 system, I stumbled over
the CPU not supporting mftbu. It just throws an illegal instruction trap.
So let's read the SPR values instead. All PPC CPUs should support them anyways.
I tested this patch on an e500v2 system where it makes qemu work and on my 970MP
system with 32-bit user space where everything still works with this patch
applied.
