The two error checks for image_boot_mode_id and image_nand_ecc_mode_id where wrong and would never fail, fix that!
This was detected by Apple's clang compiler: ---8<--- HOSTCC tools/kwbimage.o tools/kwbimage.c:553:20: warning: comparison of unsigned expression < 0 is always false [-Wtautological-compare] if (el->bootfrom < 0) { ~~~~~~~~~~~~ ^ ~ tools/kwbimage.c:571:23: warning: comparison of unsigned expression < 0 is always false [-Wtautological-compare] if (el->nandeccmode < 0) { ~~~~~~~~~~~~~~~ ^ ~ 2 warnings generated. --->8---
