STE have the same "problems" with FIFO size, see drivers/mmc/host/mmci.c
in kernel sources:

static struct variant_data variant_arm = {
        .fifosize               = 16 * 4,
        .fifohalfsize           = 8 * 4,
        .datalength_bits        = 16, 
};      

static struct variant_data variant_arm_extended_fifo = {
        .fifosize               = 128 * 4,
        .fifohalfsize           = 64 * 4,
        .datalength_bits        = 16,
};      

static struct variant_data variant_u300 = {
        .fifosize               = 16 * 4, 
        .fifohalfsize           = 8 * 4,
        .clkreg_enable          = MCI_ST_U300_HWFCEN,
        .datalength_bits        = 16,
        .sdio                   = true,
};      

static struct variant_data variant_ux500 = {
        .fifosize               = 30 * 4,
        .fifohalfsize           = 8 * 4,
        .clkreg                 = MCI_CLK_ENABLE,
        .clkreg_enable          = MCI_ST_UX500_HWFCEN,
        .datalength_bits        = 24,
        .sdio                   = true,
        .st_clkdiv              = true,
};      

static struct variant_data variant_ux500v2 = {
        .fifosize               = 30 * 4,
        .fifohalfsize           = 8 * 4,
        .clkreg                 = MCI_CLK_ENABLE,
        .clkreg_enable          = MCI_ST_UX500_HWFCEN,
        .datalength_bits        = 24,
        .sdio                   = true,
        .st_clkdiv              = true,
        .blksz_datactrl16       = true,
};      

Cheers!
