There are several platforms using arm_setup_page_tables(), which is
supposed to be Arm platform only. This creates several dependency
problems between platforms.

This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib
v2 makefile. This way it is possible to detect from C code which version
is being used and include the correct header.

The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and
moved to a common folder. This way, when in doubt, this header can be
used to guarantee compatibility, as it includes the correct header based
on XLAT_TABLES_LIB_V2.

This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so
that is now locked in xlat lib v2) and ZynqMP (where it was added as a
workaround).

Non-Arm platforms shouldn't use Arm platform code. This patch copies the
implementation of the functions in arm_helpers.S to zynqmp_helpers.S to
remove this dependency of zynqmp on Arm platforms.

Enable ARM_XLAT_TABLES_LIB_V1 as ZynqMP is using
v1 library of translation tables.

With upstream patch d323af9e

,
the usage of MAP_REGION_FLAT is referring to definition in file
include/lib/xlat_tables/xlat_tables_v2.h but while preparing
xlat tables in lib/xlat_tables/xlat_tables_common.c it is referring
to include/lib/xlat_tables/xlat_tables.h which is v1 xlat tables.
Also, ZynqMP was using v1 so defined ARM_XLAT_TABLES_LIB_V1 to
use v1 xlat tables everywhere.
This fixes the issue of xlat tables failures as it takes v2
library mmap_region structure in some files and v1 in other
files.

Add IPI mailbox service to manage Xilinx ZynqMP IPI(Inter Processors
Interrupt) access.
Signed-off-by: Wendy Liang <jliang@xilinx.com>

Previously, ZynqMP IPI in ATF is only for ZynqMP PM,
This patch is to have a ZynqMP IPI implementation to handle
both ZynqMP PM IPI requirement and IPI mailbox service requirement
which will be introduced next.

We control IPI agents registers access but not IPI buffers access in
this implementation. Each IPI mailbox user will directly access the
IPI buffers.

Pre-v8.2 platforms such as the Juno platform does not have
the Scalable Vector Extensions implemented and so the build
option ENABLE_SVE is set to zero.

This has a minor performance improvement with no functional
impact.

These source file definitions should be defined in generic
Makefiles so that all platforms can benefit. Ensure that the
symbols are properly marked as weak so they can be overridden
by platforms.

NOTE: This change is a potential compatibility break for
non-upstream platforms.

The platform.mk sets build options required for ZynqMP, but users
can still change them from the command line, like:

  make PLAT=zynqmp RESET_TO_BL31=0 CROSS_COMPILE=...

Then, the makefile shows an error message in that case:
  Using BL31 as the reset vector is only one option supported on ZynqMP.
  Please set RESET_TO_BL31 to 1.

If the option is not user-configurable, the makefile can specify
"override" to prevent users from changing it.  We do not need the
error message for the case that never happens.

Likewise, ENABLE_PLAT_COMPAT := 0 and PROGRAMMABLE_RESET_ADDRESS := 1
are mandatory to avoid build error.

Drop the current configuration options for selecting the location of
the ATF and TSP (ZYNQMP_ATF_LOCATION, ZYNQMP_TSP_RAM_LOCATION).
The new configuration provides one default setup (ATF in OCM,
BL32 in DRAM). Additionally, the new configuration options
 - ZYNQMP_ATF_MEM_BASE
 - ZYNQMP_ATF_MEM_SIZE
 - ZYNQMP_BL32_MEM_BASE
 - ZYNQMP_BL32_MEM_SIZE
can be used to freely configure the memory locations used for ATF and
secure payload.

Also, allow setting the BL33 entry point via PRELOADED_BL33_BASE.
