Hmm, sorry if I missed anything because it's too late here. But:
Why now an U-Boot patch? What's about the kernel patch you sent earlier?
The motivation for this patch came after I was debugging audio playback on mx31pdk.
I noticed that audio only worked when I used Redboot.
Comparing the sources of Redboot and U-boot I saw that the aips registers were not set.
Setting them in U-boot allowed me to get audio playback working.
Why did I send the aips setting to the kernel? Well, it is not always possible for customers to change the bootloader.
In case the bootloader does not set aips, then this should be done in the kernel.
You can also think on the possibility of someone using the mainline U-boot with a kernel that does not set aips, so the safest thing is to have such settings in the bootloader and in the kernel.
And why don't you try to create some common parts with
http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commitdiff;h=f2f7745825...
I thought about that, but I realized the AIPS settings were not exactly the same. My main goal at this point was to get the aips settings in mx31, but I can work on factoring out this code later.
