uimage_padhdr: add options to insert data into padding area

2026-07-30T06:53:14Z

Add two new command-line options, both repeatable, to write arbitrary data at specific byte offsets within the zero-filled padding area that is appended after the uImage header: -x offset:hexstring Insert raw bytes specified as a hex string -s offset:string Insert an ASCII string (without NUL terminator, since the padding is already zero-filled) Offsets are relative to the start of the padding area and accept both decimal and hexadecimal (0x-prefixed) notation. Validate that every patch fits within the configured padding before modifying the image, preventing silent data corruption. Patches are applied to the buffer before the header CRC is recalculated, so the checksum correctly covers the inserted content.

uimage_padhdr: improve error handling and cleanup

2026-07-30T06:53:14Z

Replace abrupt exit(1) calls with a 'goto out' cleanup pattern. This ensures that opened file descriptors (ifd, ofd) are properly closed and allocated memory (filebuf) is safely freed when an error occurs during execution, preventing resource leaks.

mkzynfw: rename macros from RTL93XX to RTL_OTTO

2026-06-18T06:57:58Z

Rename the board definition macros from RTL93XX to RTL_OTTO to denote they are usable for non-RTL93xx boards too. All fixed constants are shared so there is no need for a new macro. Link: https://github.com/openwrt/firmware-utils/pull/69 Signed-off-by: Jonas Jelonek
