Switch the default for the 'virt' board to not providing TrustZone
support in either the CPU or the GIC. This is primarily for the
benefit of UEFI, which currently assumes there is no TrustZone
support, and does not set the GIC up correctly if it is TZ-aware.
It also means the board is consistent about its behaviour whether
we're using KVM or TCG (KVM never has TrustZone support).
If TrustZone support is required (for instance for running test
suites or TZ-aware firmware) it can be enabled with the
"-machine secure=on" command line option.

If we directly boot a kernel in NonSecure on a system where the GIC
supports the security extensions then we must cause the GIC to
configure its interrupts into group 1 (NonSecure) rather than the
usual group 0, and with their initial priority set to the highest
NonSecure priority rather than the usual highest Secure priority.
Otherwise the guest kernel will be unable to use any interrupts.
Implement this behaviour, controlled by a flag which we set if
appropriate when the ARM bootloader code calls our ARMLinuxBootIf
interface callback.

For ARM we have a little minimalist bootloader in hw/arm/boot.c which
takes the place of firmware if we're directly booting a Linux kernel.
Unfortunately a few devices need special case handling in this situation
to do the initialization which on real hardware would be done by
firmware. (In particular if we're booting a kernel in NonSecure state
then we need to make a TZ-aware GIC put all its interrupts into Group 1,
or the guest will be unable to use them.)
Create a new QOM interface which can be implemented by devices which
need to do something different from their default reset behaviour.
The callback will be called after machine initialization and before
first reset.

Although we were correctly handling interrupts becoming active

by setting the 'active' flag for the interrupt, so reads

The running_irq and last_active arrays represent state which
doesn't exist in a real hardware GIC. The only thing we use
them for is updating the running priority when an interrupt
is completed, but in fact we can use the active-priority
registers to do this. The running priority is always the
priority corresponding to the lowest set bit in the active
priority registers, because only one interrupt at any
particular priority can be active at once.

A GICv2 has both GICC_APR<n> and GICC_NSAPR<n> registers, with
the latter holding the active priority bits for Group 1 interrupts
(usually Nonsecure interrupts), and the Nonsecure view of the
GICC_APR<n> is the second half of the GICC_NSAPR<n> registers.
Turn our half-hearted implementation of APR<n> into a proper
implementation of both APR<n> and NSAPR<n>:
* Add the underlying state for NSAPR<n>
* Make sure APR<n> aren't visible for pre-GICv2
* Implement reading of NSAPR<n>
* Make non-secure reads of APR<n> behave correctly

Priority values for the GIC are divided into a "group priority"
and a "subpriority" (with the division being determined by the
binary point register). The running priority is only determined
by the group priority of the active interrupts, not the
subpriority. In particular, this means that there can't be more
than one active interrupt at any particular group priority.

field, so implement it that way

Since the pow2floor() function is now used in a hot code path,
make it inline; for consistency, provide pow2ceil() as an inline
function too.
Because these functions use ctz64() we have to put the inline
versions into host-utils.h, so they have access to ctz64(),
and move the inline is_power_of_2() along with them.
We then need to include host-utils.h from qemu-common.h so that
the files which use these functions via qemu-common.h still have
access to them.

A couple of places in hw/pci use an inline calculation to round a
size up to the next largest power of 2. We have a utility routine
for this, so use it.
(The behaviour of the old code is different if the size value
is 0 -- it would leave it as 0 rather than rounding up to 1,
but in both cases we know the size can't be 0.
In the case where the size value had bit 31 set, the old code
would invoke undefined behaviour; the new code will give a
result of 0. Presumably that could never happen either.)

Factor out a repeated pattern in the semihosting code:
gdb_do_syscall(arm_semi_cb, "system,%s", arg0, (int)arg1+1);
/* arm_semi_cb sets env->regs[0] to the syscall return value */
return env->regs[0];
For A64 the return value will go in a different register; pull
the sequence out into its own function that passes the return
value in a static variable rather than overloading regs[0]
for the purpose, so the code will work on both A32/T32 and A64.

Fix a capitalization error in the OS X build instructions;
this was picked up in review of commit b352153f5f and intended to be
corrected before I applied it, but I accidentally didn't include it.

exec-all: Translate TCI return addresses backwards too
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Now we have the ability to flush the TLB only for specific MMU indexes,
update the AArch64 TLB maintenance instruction implementations to only
flush the parts of the TLB they need to, rather than doing full flushes.
We take the opportunity to remove some duplicate functions (the per-asid
tlb ops work like the non-per-asid ones because we don't support
flushing a TLB only by ASID) and to bring the function names in line
with the architectural TLBI operation names.

Guest CPU TLB maintenance operations may be sufficiently
specialized to only need to flush TLB entries corresponding
to a particular MMU index. Implement cputlb functions for
this, to avoid the inefficiency of flushing TLB entries
which we don't need to.

Apply the correct conditions in the ats_access() function for
the ATS12NSO* address translation operations:
* succeed at EL2 or EL3
* normal UNDEF trap from NS EL1
* trap to EL3 from S EL1 (only possible if EL3 is AArch64)
(This change means they're now available in our EL3-supporting
CPUs when they would previously always UNDEF.)

Some coprocessor register access functions need to be able
to report "trap to EL3 with an 'uncategorized' syndrome";
add the necessary CPAccessResult enum and handling for it.
I don't currently know of any registers that need to trap
to EL2 with the 'uncategorized' syndrome, but adding the
_EL2 enum as well is trivial and fills in what would
otherwise be an odd gap in the handling.

Wire up the AArch64 EL2 and EL3 address translation operations
(AT S12E1*, AT S12E0*, AT S1E2*, AT S1E3*), and correct some
errors in the ats_write64() function in previously unused code
that would have done the wrong kind of lookup for accesses from
EL3 when SCR.NS==0.
