[meta-xilinx] Disable U-Boot MMC?

The reason I ask is that when I try to program the QSPI flash with this
BOOT.bin

//arch = zynqmp; split = false; format = BIN
the_ROM_image:
{
 [fsbl_config]a53_x64
 [bootloader]E:\gFEX_pre_production\image\zu19eg_3\zu19eg_3.sdk\fsbl_a53\Debug\fsbl_a53.elf
 [destination_cpu =
pmu]E:\gFEX_pre_production\image\giordon\linux\gfex-prototype3\pmu-gfex-prototype3.elf
 [destination_device =
pl]E:\gFEX_pre_production\image\zu19eg_3\zu19eg_3.sdk\zcu19eg_top_hw_platform_0\zcu19eg_top.bit
 [destination_cpu = a53-0, exception_level = el-3,
trustzone]E:\gFEX_pre_production\image\giordon\linux\gfex-prototype3\arm-trusted-firmware.elf
 [destination_cpu = a53-0, exception_level =
el-2]E:\gFEX_pre_production\image\giordon\linux\gfex-prototype3\u-boot.elf
}

the u-boot line hangs with "MMC: " and nothing else. I think this is
related to the SD not working at all.
