This patch fixes the build time condition deciding whether the

Fix handling of spurious interrupts in BL3_1
There are couple of issues with how the interrupt routing framework in BL3_1
handles spurious interrupts.
1. In the macro 'handle_interrupt_exception', if a spurious interrupt is
detected by plat_ic_get_pending_interrupt_type(), then execution jumps to
'interrupt_exit_\label'. This macro uses the el3_exit() function to return to
the original exception level. el3_exit() attempts to restore the SPSR_EL3 and
ELR_EL3 registers with values from the current CPU context. Since these
registers were not saved in this code path, it programs stale values into
these registers. This leads to unpredictable behaviour after the execution of
the ERET instruction.
2. When an interrupt is routed to EL3, it could be de-asserted before the
GICC_HPPIR is read in plat_ic_get_pending_interrupt_type(). There could be
another interrupt pending at the same time e.g. a non-secure interrupt. Its
type will be returned instead of the original interrupt. This would result in
a call to get_interrupt_type_handler(). The firmware will panic if the
handler for this type of interrupt has not been registered.
This patch fixes the first problem by saving SPSR_EL3 and ELR_EL3 early in the
'handle_interrupt_exception' macro, instead of only doing so once the validity
of the interrupt has been determined.
The second problem is fixed by returning execution back to the lower exception
level through the 'interrupt_exit_\label' label instead of treating it as an
error condition. The 'interrupt_error_\label' label has been removed since it is
no longer used.

PSCI: Set ON_PENDING state early during CPU_ON
In the debug build of the function get_power_on_target_afflvl(), there is a
check to ensure that the CPU is emerging from a SUSPEND or ON_PENDING state.
The state is checked without acquiring the lock for the CPU node. The state
could be updated to ON_PENDING in psci_afflvl_on() after the target CPU has
been powered up. This results in a race condition which could cause the
check for the ON_PENDING state in get_power_on_target_afflvl() to fail.
This patch resolves this race condition by setting the state of the target
CPU to ON_PENDING before the platform port attempts to power it on. The
target CPU is thus guaranteed to read the correct the state. In case
the power on operation fails, the state of the CPU is restored to OFF.

the AP cores are still able to communicate with the SCP.
This patch focuses on the mandatory changes to make it work. The
design of this code needs to be improved but this will come in

The main changes are:
- MHU communication protocol
- The command ID and payload size are no longer written into the
MHU registers directly. Instead, they are stored in the payload
area. The MHU registers are now used only as a doorbell to kick
off messages. Same goes for any command result, the AP has to
pick it up from the payload area.
- SCP Boot Protocol
- The BL3-0 image is now expected to embed a checksum. This
checksum must be passed to the SCP, which uses it to check the
integrity of the image it received.
- The BL3-0 image used to be transferred a block (4KB)
at a time. The SCP now supports receiving up to 128KB at a
time, which is more than the size of the BL3-0 image.
Therefore, the image is now sent in one go.
- The command IDs have changed.
- SCPI Protocol
- The size of the SCPI payload has been reduced down from 512
bytes to 256 bytes. This changes the base address of the
AP-to-SCP payload area.
- For commands that have a response, the response is the same SCPI
header that was sent, except for the size and the status, which
both must be updated appropriately. Success/Failure of a command
is determined by looking at the updated status code.
- Some command IDs have changed.

Add common ARM and CSS platform code
This major change pulls out the common functionality from the
FVP and Juno platform ports into the following categories:
* (include/)plat/common. Common platform porting functionality that
typically may be used by all platforms.
* (include/)plat/arm/common. Common platform porting functionality
that may be used by all ARM standard platforms. This includes all
ARM development platforms like FVP and Juno but may also include
non-ARM-owned platforms.
* (include/)plat/arm/board/common. Common platform porting
functionality for ARM development platforms at the board
(off SoC) level.
* (include/)plat/arm/css/common. Common platform porting
functionality at the ARM Compute SubSystem (CSS) level. Juno
is an example of a CSS-based platform.
* (include/)plat/arm/soc/common. Common platform porting
functionality at the ARM SoC level, which is not already defined
at the ARM CSS level.
No guarantees are made about the backward compatibility of
functionality provided in (include/)plat/arm.
Also remove any unnecessary variation between the ARM development
platform ports, including:
* Unify the way BL2 passes `bl31_params_t` to BL3-1. Use the
Juno implementation, which copies the information from BL2 memory
instead of expecting it to persist in shared memory.
* Unify the TZC configuration. There is no need to add a region
for SCP in Juno; it's enough to simply not allow any access to
this reserved region. Also set region 0 to provide no access by
default instead of assuming this is the case.
* Unify the number of memory map regions required for ARM
development platforms, although the actual ranges mapped for each
platform may be different. For the FVP port, this reduces the
mapped peripheral address space.
These latter changes will only be observed when the platform ports
are migrated to use the new common platform code in subsequent
patches.

Set group status of PPIs and SGIs correctly on GICv3 systems
On a GICv2 system, the group status of PPIs and SGIs is set in the GICD_IGROUPR0
register. On a GICv3 system, if affinity routing is enabled for the non-secure
state, then the group status of PPIs and SGIs should be set in the GICR_IGROUPR0
register. ARM Trusted firmware sets the group status using the GICv2
sequence. On a GICv3 system, if the group status of an interrupt is set to Group
1 through a write to the GICD_IGROUPR0, then the GICR_IGROUPR0 is updated as
well.
The current sequence is incorrect since it first marks all PPIs and SGIs as
Group 1. It then clears the bits in GICD_IGROUPR0 corresponding to secure
interrupts to set their group status to Group 0. This operation is a no-op. It
leaves the secure generic timer interrupt (#29) used by the TSP marked as Group
1. This causes the interrupt to interfere with the execution of non-secure
software. Once an interrupt has been marked as Group 1, the GICR_IGROUPR0 should
be programmed to change its group status.
This patch rectifies this issue by setting the group status of only the
non-secure PPI and SGIs to Group 1 in the first place. GICD_IGROUPR0 resets to
0. So secure interrupts are marked as Group 0 by default.
