The API is not very useful these days, since it doesn't support driver model. It is laborious to add new functions to the API as there are so many needed. A better approach would be to create a library containing all of U-Boot, then have the API be generated by a script containing a list of functions, perhaps with wildcards. Then a stub could be created, with a list of entry points, which links with and calls through into the library. In preparation for heading in this direction, rename some of the existing files and directories: - examples/api -> examples/legacy_api - include/api*.h -> include/legacy_api*.h - API_BUILD to LEGACY_API_BUILD Co-developed-by: Claude <noreply@anthropic.com>
