Hmm, sorry, I'm not sure I completely understood.

Do you want to say that you want a directory "cpu/arm_cortexa8/" where 
the common files for Corex-A8 CPUs are located and then a directory 
"cpu/arm_cortexa8/omap3" where the OMAP3 common stuff is stored?

If this is correct, from theory I completely agree. *But*: From 
practical point of view regarding the patch we are talking about here, 
we just don't know what Corex-A8 CPU common code might be. As I know 
there is no "xxx" (with xxx != OMAP3) yet, so it's hard to know what 
will be common. So we moved all OMAP3 common code for all three buards 
we currently support to omap3 directory.

So for the time being, I propose to create /cpu/arm_cortexa8/omap3 
with all files in this directory and no files in /cpu/arm_cortexa8 
yet. This can change later, files from omap3/ can move to 
/cpu/arm_cortexa8/ when we get more Cortex-A8 SoCs/chips and get an 
idea what might be common.

Yes, as "xxx" doesn't exist yet ;)

But my question here was if we can do directory moves/renames in git 
after/while patch is applied or if new patches with directory changes 
are needed on mailing list? Directory move/rename is easy in git, 
while doing this with patches to mailing list may result in 
unnecessary traffic.

Thanks

Dirk
