Hi,
I am picking up on this old thread. My main point is that I think the armv7 cache implementation is a good start and should go into U-Boot. Aneesh are you planning another patch set? Also see below:

How much of this is actually needed in the context of U-Boot?
Please see above. As far as I know OMAP doesn't do DMA in U-Boot.
Devices like USB oth Ethernet don't use DMA for data transfers?
Ethernet support is not upstreamed yet. USB doesn't seem to be using DMA on a quick check.
There is DMA in the USB EHCI side and this also does d cache range invalidate / flush.
