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> |
