I'll do a more comprehensive search for these flags. When I did my
testing on the AM3517, I didn't notice these, but I see now that
others might. I'll do a multi-patch series to first address the
multi-block, then omap3-ldp.dts, then migrate the omap3.dtsi to the
new driver while dropping the flags, and lastly update the individual
boards accordingly. I just have one question below.

Should I update the driver and binding to add ti,omap3-pre-es3-sdhci
to set that flag, or should we create a boolean (maybe
'ti,sdhci-no-multiblock') to the device tree options for that driver?
