Mpc8536, p2020, and the other current DPAA silicon (e.g. p5020, p3041)
support it.

In sdhci_add_host()
We have the following
...
mmc->caps |= MMC_CAP_SDIO_IRQ | MMC_CAP_ERASE | MMC_CAP_CMD23;
if (host->quirks & SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12)
host->flags |= SDHCI_AUTO_CMD12;
/* Auto-CMD23 stuff only works in ADMA or PIO. */
