how come ???

functionally no, but (hypothetical situation) and if on
omap4/5/6/whatever, omap controller supports a bigger bus width then
you'll have to add a line like:
+ if (mmc_slot(host).wires == 16)
+ mmc->caps |= (MMC_CAP_16_BIT_DATA | MMC_CAP_8_BIT_DATA |
+ MMC_CAP_4_BIT_DATA);
- if (mmc_slot(host).wires == 8)
+ else if (mmc_slot(host).wires == 8)
do you see the problem ?? In my opinion it doesn't scale well.
