Eric Auger bf424a1216 hw/arm/virt: Rename highmem IO regions
In preparation for a split of the memory map into a static
part and a dynamic part floating after the RAM, let's rename the
regions located after the RAM

Peter Maydell 3733f80308 hw/arm/armsse: Make 0x5... alias region work for per-CPU devices
The region 0x40010000 .. 0x4001ffff and its secure-only alias
at 0x50010000... are for per-CPU devices. We implement this by
giving each CPU its own container memory region, where the
per-CPU devices live. Unfortunately, the alias region which
makes devices mapped at 0x4... addresses also appear at 0x5...
is only implemented in the overall "all CPUs" container. The
effect of this bug is that the CPU_IDENTITY register block appears
only at 0x4001f000, but not at the 0x5001f000 alias where it should
also appear. Guests (like very recent Arm Trusted Firmware-M)
which try to access it at 0x5001f000 will crash.

Fix this by moving the handling for this alias from the "all CPUs"
container to the per-CPU container. (We leave the aliases for
0x1... and 0x3... in the overall container, because there are
no per-CPU devices there.)

Peter Maydell 91c1e9fcbd hw/arm/armsse: Support dual-CPU configuration
The SSE-200 has two Cortex-M33 CPUs. These see the same view
of memory, with the exception of the "private CPU region" which
has per-CPU devices. Internal device interrupts for SSE-200
devices are mostly wired up to both CPUs, with the exception of
a few per-CPU devices. External GPIO inputs on the SSE-200
device are provided for the second CPU's interrupts above 32,
as is already the case for the first CPU.

Refactor the code to support creation of multiple CPUs.
For the moment we leave all CPUs with the same view of
memory: this will not work in the multiple-CPU case, but
we will fix this in the following commit.

Peter Maydell 4b635cf7a9 hw/arm/armsse: Make SRAM bank size configurable
For the IoTKit the SRAM bank size is always 32K (15 bits); for the
SSE-200 this is a configurable parameter, which defaults to 32K but
can be changed when it is built into a particular SoC. For instance
the Musca-B1 board sets it to 128K (17 bits).

Make the bank size a QOM property. We follow the SSE-200 hardware in
naming the parameter SRAM_ADDR_WIDTH, which specifies the number of
address bits of a single SRAM bank.

The Arm SSE-200 Subsystem for Embedded is a revised and
extended version of the older IoTKit SoC. Prepare for
adding a model of it by refactoring the IoTKit code into
an abstract base class which contains the functionality,
driven by a class data block specific to each subclass.
(This is the same approach used by the existing bcm283x
SoC family implementation.)

Peter Maydell 93dbd10347 hw/arm/iotkit: Rename IoTKit to ARMSSE
The Arm IoTKit was effectively the forerunner of a series of
subsystems for embedded SoCs, named the SSE-050, SSE-100 and SSE-200:
https://developer.arm.com/products/system-design/subsystems
These are generally quite similar, though later iterations have
extra devices that earlier ones do not.

We want to add a model of the SSE-200, which means refactoring the
IoTKit code into an abstract base class and subclasses (using the
same design that the bcm283x SoC and Aspeed SoC family
implementations do). As a first step, rename the IoTKit struct and
QOM macros to ARMSSE, which is what we're going to name the base
class. We temporarily retain TYPE_IOTKIT to avoid changing the
code that instantiates a TYPE_IOTKIT device here and then changing
it back again when it is re-introduced as a subclass.

Philippe Mathieu-Daudé ead07aa4ef hw/arm/allwinner-a10: Add the 'A' SRAM and the SRAM controller
From the "A10 User Manual V1.20" p.29: "3.2. Memory Mapping" and:

 7. System Control
  7.1. Overview

  A10 embeds a high-speed SRAM which has been split into five segments.
  See detailed memory mapping in following table:

  Area          Address        Size (Bytes)
   A1    0x00000000-0x00003FFF 16K
   A2    0x00004000-0x00007FFF 16K
   A3    0x00008000-0x0000B3FF 13K
   A4    0x0000B400-0x0000BFFF  3K

Since for emulation purpose we don't need the segmentations, we simply define
the 'A' area as a single 48KB SRAM.

We don't implement the following others areas:
- 'B': 'Secure RAM' (64K),
- 'C': Debug/ISP SRAM
- 'D': USB SRAM

The nRF51 is a Cortex-M0 microcontroller with an on-board radio module,
plus other common ARM SoC peripherals.

Peter Maydell 132b475a73 hw/arm/iotkit: Wire up the lines for MSCs
The IoTKit doesn't have any MSCs itself but it does need
some wiring to connect the external signals from MSCs
in the outer board model up to the registers and the
NVIC IRQ line.

We also need to expose a MemoryRegion corresponding to
the AHB bus, so that MSCs in the outer board model can
use that as their downstream port. (In the FPGA this is
the "AHB Slave Expansion" ports shown in the block
diagram in the AN505 documentation.)

Stefan Hajnoczi a1c5a06224 hw/arm: make bitbanded IO optional on ARMv7-M
Some ARM CPUs have bitbanded IO, a memory region that allows convenient
bit access via 32-bit memory loads/stores.  This eliminates the need for
read-modify-update instruction sequences.

This patch makes this optional feature an ARMv7MState qdev property,
allowing boards to choose whether they want bitbanding or not.

Status of boards:
 * iotkit (Cortex M33), no bitband
 * mps2 (Cortex M3), bitband
 * msf2 (Cortex M3), bitband
 * stellaris (Cortex M3), bitband
 * stm32f205 (Cortex M3), bitband

As a side-effect of this patch, Peter Maydell noted that the Ethernet
controller on mps2 board is now accessible.  Previously they were hidden
by the bitband region (which does not exist on the real board).

Luc Michel 75b749af0c xlnx-zynqmp: Improve GIC wiring and MMIO mapping
This commit improve the way the GIC is realized and connected in the
ZynqMP SoC. The security extensions are enabled only if requested in the
machine state. The same goes for the virtualization extensions.

All the GIC to APU CPU(s) IRQ lines are now connected, including FIQ,
vIRQ and vFIQ. The missing CPU to GIC timers IRQ connections are also
added (HYP and SEC timers).

The GIC maintenance IRQs are back-wired to the correct GIC PPIs.

Finally, the MMIO mappings are reworked to take into account the ZynqMP
specifics. The GIC (v)CPU interface is aliased 16 times:
  * for the first 0x1000 bytes from 0xf9010000 to 0xf901f000
  * for the second 0x1000 bytes from 0xf9020000 to 0xf902f000
Mappings of the virtual interface and virtual CPU interface are mapped
only when virtualization extensions are requested. The
XlnxZynqMPGICRegion struct has been enhanced to be able to catch all
this information.

Let's cache config data to avoid fetching and parsing STE/CD

We put in place a per-smmu mutex to protect the config cache. This
will be useful too to protect the IOTLB cache. The caches can be
accessed without BQL, ie. in IO dataplane. The same kind of mutex was
put in place in the intel viommu.
