With this change we have more chances to catch build issues during
refactoring.
The board is added to get build coverage, it is not verified if it

No need for the new EBI binding atm, so no reas

The DT file in patch 11 looks like a file that would be a good linux

Add helper that can be used to disable highcapacity support
