SoC files OK, though would be better to have a board so it can be seen that the files are error free and can build

Thanks of your advice.
I verified it with local board files before submitting this PR.

i.e: Based on prior PR feedback, some reviewer suggested splitting small PRs into fewer files, so I separated it into an SoC PR and a board PR.

It's fine to have a SoC and board PR - so long as they are in different commits i.e. not one huge commit with files all over the place
