Manish Pandey f91a8e4c2c n1sdp: update platform macros for dual-chip setup
N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link  for now only dual-chip is
supported.

A single instance of TF-A runs on master chip which should be aware of
slave chip's CPU and memory topology.

This patch updates platform macros to include remote chip's information
and also ensures that a single version of firmware works for both single
and dual-chip setup.

Manoj Kumar de8bc83ee9 n1sdp: add code for DDR ECC enablement and BL33 copy to DDR
N1SDP platform supports RDIMMs with ECC capability. To use the ECC
capability, the entire DDR memory space has to be zeroed out before
enabling the ECC bits in DMC620. Zeroing out several gigabytes of
memory from SCP is quite time consuming so functions are added that
zeros out the DDR memory from application processor which is
much faster compared to SCP. BL33 binary cannot be copied to DDR memory
before enabling ECC so this is also done by TF-A from IOFPGA-DDR3
memory to main DDR4 memory after ECC is enabled.

Original PLAT_PHY_ADDR_SPACE_SIZE was limited to 36-bits with which
the entire DDR space cannot be accessed as DRAM2 starts in base
0x8080000000. So these macros are redefined for all ARM platforms.

Aditya Angadi b0c97dafe0 plat/arm: introduce wrapper functions to setup secure watchdog
The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.

So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.

Antonio Nino Diaz bd9344f670 plat/arm: Sanitise includes
Use full include paths like it is done for common includes.

This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

Antonio Nino Diaz 234bc7f88e plat/arm: Fix header dependencies
From now on, platform_def.h must include any header with definitions that
are platform-specific (like arm_def.h) and the included headers mustn't
include back platform_def.h, and shouldn't be used by other files. Only
platform_def.h should be included in other files. This will ensure that all
needed definitions are present, rather than needing to include all the
headers in all the definitions' headers just in case.

This also prevents problems like cyclic dependencies.

Deepak Pandey a15f38cf4f plat/arm/n1sdp: define the uart constants for N1SDP
This patch removes the dependency of the N1SDP on soc
css defines in order to let the N1SDP platform port
define the uart related constants.

Antonio Nino Diaz 09d40e0e08 Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Deepak Pandey 80d37c2872 plat/arm: Introduce the N1SDP.
This patch adds support for the N1SDP (NeoVerse N1 System Development
Platform). It is an initial port and additional features are expected
to be added later.

The port includes only BL31 support as the System Control Processor
(SCP) is expected to take the role of primary boatloader
