This\nkeeps compressed type conversion centralized and makes future attribute\nextensions easier and less error-prone.\n\nThe last patch adds LZ4 support in Kconfig/build flags, parser mappings,\nruntime decompression, Lua helper mapping, and related documentation.\n\nComments and reviews are welcome.\n\nThanks,\nHe Yong\n\nHe Yong (4):\n util: add compressed-string parser and img setter macros\n parser: refactor stream attribute parsing\n corelib: refactor Lua image attribute parsing\n compress: add lz4 decompression support\n\n Kconfig | 8 ++\n Makefile.deps | 4 +\n Makefile.flags | 4 +\n ci/setup.sh | 1 +\n core/cpio_utils.c | 101 +++++++++++++++-\n core/util.c | 23 ++++\n corelib/lua_interface.c | 218 ++++++++++++++++++++--------------\n doc/source/sw-description.rst | 2 +-\n doc/source/swupdate.rst | 2 +-\n handlers/swupdate.lua | 2 +-\n include/util.h | 19 +++\n parser/parse_external.c | 175 ++++++++++++++++-----------\n parser/parser.c | 11 +-\n 13 files changed, 400 insertions(+), 170 deletions(-)"}
