2019-12-13Add NXP's i.MX8 SoCs system controller console supportAnson Huang
NXP's i.MX8 SoCs with system controller inside support outputting debug message to system controller's console via calling SCFW API, since TF-A shares debug console with Linux kernel which will have confliction if Linux kernel and TF-A's console are both enabled, this patch adds support for switching TF-A debug console to system controller to easy TF-A debug.

2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("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.

2018-08-03Create a library file for libcRoberto Vargas
TF Makefile was linking all the objects files generated for the c library instead of creating a static library that could be used in the linking stage. Change-Id: I721daea097e9b13cbb42c9f8eaa2af8fea0799cf Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>
