From: Andre Przywara <andre.przywara@arm.com> The A64 has 3 MMC controllers, one of them being especially targeted to eMMC. Among other things, it has a data strobe signal and a 8 bits data width. The two other are more usual controllers that will have a 4 bits width at most and no data strobe signal, which limits it to more usual SD or MMC peripherals.
