Uh. Did you just propose SPI framework #6 for u-boot?
How about we try to modify one of the existing ones so that it can be useful for everything? That is, spi flash, spi eeproms, LCD panels, sensors, etc.?
In fact, I did post a patch that attempted this not so long ago, but I never got any response:

I'd really like to see a common layer for SPI flash though, so I don't mean to criticise your effort. But it would be nice if not every new SPI client came with its own low-level SPI functions...
i know exactly where you're coming from, so dont sweat it. my purpose was to get things integrated and then take a look at the existing pieces and unify them. easier i think to have known working code to throw at a common framework than code for hypothetical uses we cant actually break our teeth on. -mike
