This series brings our zlib code more up to date. However, it drops an important performance improvement that is required on some of our supported platforms in order to boot Linux before the watchdog resets the system. Furthermore, the "post increment" version of this performance loop was not tested, so while we can fix it, it would then require re-testing all platforms. At this point in time, we will revert updating zlib (which has had a potential security issue since 2016) and fix this in the v2024.10 release. This reverts commit4914263c9a, reversing changes made toef8ef5f77c. Reported-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Tom Rini <trini@konsulko.com>
