I could live with cpu/freescale/imx. Presumably it would be built in via the SOC value?
Do we really need the "freescale" subdirectory here? Maybe cpu/arm_imx would be a shorter and more descriptive name?

I think it is a matter of taste. You actually do not need to have any subdirectories in U-boot at all. Some people prefer using a directory structure to hide information which is of little interest to them
There seems to be shared code for PowerPCs and NIOS(2). Do we want to create new subdirectories for every share, cluttering up "cpu"?
I think the likelyhood for shared code between different Freescale PPC is higher than shared code between IBM and Freescale PPC. Therefore a "freescale" directory could also contains shared PPC code.
Some people would like to have consistency making it easy to find where things are located.
If you look at what is driving duplication, then you find that the peripherals are either developed inside a semiconductor company, or they are licensed from an IP provider.
It makes a lot of sense therefore to dedicate directories to the providers of IP: ARM is a provider, but so are also Freescale, Atmel and others.
