util/ifdtool/ifdtool.c: Clean up
- Remove functions that are only called in one place. - Add warning if user doesn't supply a platform, since that can lead to dumps/layouts that do not include all IFD regions without the user even reliazing it. - Inform the User if IFD or Flashmap is not found. - Inform the User if there is not a single match between FMAP and IFD region - Avoid printing usage if not specifically asked by the user. It tends to obfuscate the original error message. - Keep indentation consistent throughout the file. - Remove typedefs (coreboot coding style) Signed-off-by: Maximilian Brune <maximilian.brune@9elements.com> Change-Id: I7bbce63ecb2e920530394766f58b5ea6f72852e9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/73448 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lean Sheng Tan <sheng.tan@9elements.com>
