However, this approach is fragile due to Kconfig options potentially changing across different releases. For example, CONFIG_OF_PRIOR_STAGE has been replaced by CONFIG_BOARD since v2022.01 release, and CONFIG_TEXT_BASE has been moved to the 'General setup' menu from the 'Boot options' menu in v2024.01 release. This update aims to make the S-mode U-Boot image build instructions future-proof. It leverages the 'config' script provided in the U-Boot source tree to edit the .config file, followed by a `make olddefconfig`. Validated with U-Boot v2024.01 release.
