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.

2017-06-05CSS: Add SCMI driver for SCPSoby Mathew
This patch adds the SCMI driver for communicating with SCP. The power domain management and system power management protocol of the SCMI specification[1] is implemented in the driver. The SCP power management abstraction layer for SCMI for CSS power management is also added. A new buid option `CSS_USE_SCMI_DRIVER` is introduced to select SCMI driver over SCPI.
