What's the point of this command exactly? I can see the point of range flushes (and invalidates) in the code for drivers that use DMA, but as a shell command, I fail to see the interest of it.
I am actually expecting this question. We have a situation that an application is copied by u-boot to its destination in memory. The code needs to be "seen" in the main memory. Without flushing cache, it is only visible to cores.
