This might not be a too widespread use of U-Boot, but I do have one
configuration that boots from FPGA and loads Linux via TFTP. Due to size
constraints in FPGA onchip RAM, I have MMC disabled completely. This
patch gives me a warning in this case.
I can live with that as I know I have MMC disabled and don't this
warning for my other configs though. Just wanted to let you know, as you
complained about getting no replies to this thread ;-)
