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.

2018-02-08zlib: Fix build error when LOG_LEVEL=50Sandrine Bailleux
When enabling VERBOSE() traces, the zlib library fails to compile because of an incompatible format specifier string. Fix that. Change-Id: I74ff1c8dc2e6157ee982f7754bce4504599e3013 Signed-off-by: Sandrine Bailleux <sandrine.bailleux@arm.com>
2018-02-02zlib: add gunzip() supportMasahiro Yamada
This commit adds some more files to use zlib from TF. To use zlib, ->zalloc and ->zfree hooks are needed. The implementation depends on the system. For user-space, the libc provides malloc() and friends. Unfortunately, ARM Trusted Firmware does not provide malloc() or any concept of dynamic memory allocation. I implemented very simple calloc() and free() for this. Stupidly, zfree() never frees memory, but it works enough for this. The purpose of using zlib is to implement gunzip() - this function takes compressed data from in_buf, then dumps the decompressed data to oub_buf. The work_buf is used for memory allocation during the decompress. Upon exit, it updates in_buf and out_buf. If successful, in_buf points to the end of input data, out_buf to the end of the decompressed data. To use this feature, you need to do: - include lib/zlib/zlib.mk from your platform.mk - add $(ZLIB_SOURCES) to your BL*_SOURCES Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-02-02zlib: import zlib files from zlib 1.2.11Masahiro Yamada
Import the following files from zlib 1.2.11: adler32.c crc32.c crc32.h inffast.c inffast.h inffixed.h inflate.c inflate.h inftrees.c inftrees.h zconf.h zlib.h zutil.c zutil.h The original tarball is available from http://zlib.net/ The zlib is free software, distributed under the zlib license. The license text is included in the "zlib.h" file. It should be compatible with BSD-3-Clause. The zlib license is included in the SPDX license list available at https://spdx.org/licenses/, but I did not add the SPDX license tag to the imported files above, to keep them as they are in the upstream project. This seems the general policy for ARM Trusted Firmware, as SPDX License Identifier was not added to files imported from FreeBSD. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
