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.

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.

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>	7 years ago

zlib: Fix build error when LOG_LEVEL=50

When enabling VERBOSE() traces, the zlib library fails to compile
because of an incompatible format specifier string. Fix that.

zlib: add gunzip() support

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

zlib: import zlib files from zlib 1.2.11

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.
