Merge patch series "Clean-up patch set for MbedTLS integration"WIP/22May2024-next
Raymond Mao <raymond.mao@linaro.org> says: This patch set is picked from the previously posted serie: "[RFC] Integrate MbedTLS v3.6 LTS with U-Boot" They are not directly related to MbedTLS integration, but the prerequisite for a few clean-up, refactoring and minor fixes. For V2, the linker script patch is dropped and added one patch to move the snprintf to stdio.h
