bcmsdhost* at fdt?
sdmmc* at bcmsdhost?

The bcmsdhost driver provides support for the SD controllers integrated on Broadcom BCM283x and BCM2711 SoCs. The driver uses the bcmdmac(4) DMA controller to provide DMA support.

The sdmmc(4) subsystem performs SD/MMC transactions to communicate with whatever SD devices are inserted into the card slot or directly connected to the controller.
