There is one drawback though, the slowest READ_FROM_CACHE command cannot run above 54MHz. Because of that, we need to set a limit for these chips on the basic READ_FROM_CACHE variant. Duplicating this list is not a problem because these chips have DTR support, and the list of supported variants will diverge from all the other chips when adding support for it.
