* libc: fix sparse warning for __assert()Masahiro Yamada2019-09-111-4/+4
| | | | | | | | | | | | | | Sparse warns this: lib/libc/assert.c:29:6: error: symbol '__assert' redeclared with different type (originally declared at include/lib/libc/assert.h:36) - different modifiers Add __dead2 to match the header declaration and C definition. I also changed '__dead2 void' to 'void __dead2' for the consistency with other parts.

* Sanitise includes across codebaseAntonio Nino Diaz2019-01-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* libc: Remove non-Arm filesAntonio Nino Diaz2018-08-221-77/+0
| | | | | | | | | Remove all files that don't have only Arm copyright. This is the first step to cleanup the C library in this repository. They will be re-added in the following patches. Change-Id: I72c40a1620d1df3228fc397ec695d569a20245fd Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
* Create a library file for libcRoberto Vargas2018-08-031-0/+77
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>
