PCIE0R1 security and override registers need to be preserved across
system suspend. Adding them to system suspend save register list.
Due to addition of above registers, increasing context save memory

Many simulation/emulation platforms do not support this hardware block
leading to SErrors during register accesses.

This patch conditionally accesses the registers from this block only
on actual Si and FPGA platforms.

This patch organizes the platform memory/mmio map, so that the base
addresses for the apertures line up in ascending order. This makes
it easier for the xlat_tables_v2 library to create mappings for each
mmap_add_region call.

The previous bootloader is not able to pass boot params wider than
32-bits due to an oversight in the scratch register being used. A
new secure scratch register #75 has been assigned to pass the higher
bits.

This patch adds support to parse the higher bits from scratch #75
and use them in calculating the base address for the location of
the boot params.

Scratch #75 format
====================
31:16 - bl31_plat_params high address
15:0 - bl31_params high address

HW bug in third party PCIE IP - PCIE datapath hangs when there are
more than 28 outstanding requests on data backbone for x1 controller.

Suggested SW WAR is to limit reorder_depth_limit to 16 for
PCIE 1W/2AW/3W clients.

-PTCR is ISO client so setting it to FORCE_NON_COHERENT.
-MPCORER, MPCOREW and MIU0R/W to MIU7R/W clients itself will provide
ordering so no need to override from mc.
-MIU0R/W to MIU7R/W clients registers are not implemented in tegrasim
so skipping it for simulation.
-All the clients need to set CGID_TAG_ADR to maintain request ordering
within a 4K boundary.

Memory clients are divided in to ISO/NonISO/Order/Unordered/Low
BW/High BW. Based on the client types, HW team recommends, different
memory ordering settings, IO coherency settings and SMMU register settings
for optimized performance of the MC clients.

For example ordered ISO clients should be set as strongly ordered and
should bypass SCF and directly access MC hence set as
FORCE_NON_COHERENT. Like this there are multiple recommendations
for all of the MC clients.

This change sets all these MC registers as per HW spec file.

Due to a hardware bug PVA may perform memory transactions which
cause coalescer faults. This change works around the issue by
disabling coalescer for PVA0RDC and PVA1RDC.

Force memory transactions from seswr and sesrd as coherent_snoop from
no-override. This is necessary as niso clients should use coherent
path.

Presently its set as FORCE_COHERENT_SNOOP. Once SE+TZ is enabled
with SMMU, this needs to be replaced by FORCE_COHERENT.

- SC7 requires all the cluster groups to be in CG7 state, else
  is_sc7_allowed will get denied
- As a WAR while requesting CC6, request CG7 as well
- CG7 request will not be honored if it is not last core in Cluster
  group
- This is just to satisfy MCE for now as CG7 is going to be defeatured

Out of two possible implementation of Secure Partition Manager(SPM)
currently only Management mode (MM) design is supported and the support
for SPM based on SPCI Alpha 1 prototype has been removed.

Earlier both implementation used common build flag "ENABLE_SPM" but it
has since been decoupled and MM uses a separate build FLAG "SPM_MM".

Instructions to build it for FVP was still using "ENABLE_SPM", which has
beend corrected in this patch.

Even though ERET always causes a jump to another address, aarch64 CPUs
speculatively execute following instructions as if the ERET
instruction was not a jump instruction.
The speculative execution does not cross privilege-levels (to the jump
target as one would expect), but it continues on the kernel privilege
level as if the ERET instruction did not change the control flow -
thus execution anything that is accidentally linked after the ERET
instruction. Later, the results of this speculative execution are
always architecturally discarded, however they can leak data using
microarchitectural side channels. This speculative execution is very
reliable (seems to be unconditional) and it manages to complete even
relatively performance-heavy operations (e.g. multiple dependent
fetches from uncached memory).

This was fixed in Linux, FreeBSD, OpenBSD and Optee OS:
