Patch 253cb831 [zlib: add watchdog reset call] added already a few watchdog reset calls to the new zlib U-Boot port. But on some boards this is not enough. Additional calls are needed on boards with short watchdog timeouts.
This was detected and tested on the lwmon5 board with a very short watchdog timeout. Without this patch, the board resets during Linux kernel decompression. With it, the decompression succeeds.
