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.

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.

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.

In order to support SEPARATE_NOBITS_REGION for Arm platforms, we need to load
BL31 PROGBITS into secure DRAM space and BL31 NOBITS into SRAM. Hence mandate
the build to require that ARM_BL31_IN_DRAM is enabled as well.

Naturally with SEPARATE_NOBITS_REGION enabled, the BL31 initialization code
cannot be reclaimed to be used for runtime data such as secondary cpu stacks.

Memory map for BL31 NOBITS region also has to be created.

Since BL31 PROGBITS and BL31 NOBITS sections are going to be
in non-adjacent memory regions, potentially far from each other,
some fixes are needed to support it completely.

1. adr instruction only allows computing the effective address
of a location only within 1MB range of the PC. However, adrp
instruction together with an add permits position independent
address of any location with 4GB range of PC.

2. Since BL31 _RW_END_ marks the end of BL31 image, care must be
taken that it is aligned to page size since we map this memory
region in BL31 using xlat_v2 lib utils which mandate alignment of
image size to page granularity.
