yes. I feel the same also.

So you want me send to an updated version of :

        http://lists.nongnu.org/archive/html/qemu-arm/2016-06/msg00698.html

as a prereq ? 

Now that we have done the cleanups in U-Boot, we can pull from :

https://github.com/openbmc/u-boot/blob/v2016.07-aspeed-openbmc/arch/arm/include/asm/arch-aspeed/regs-scu.h

to get the definitions. I will add that.

ok.

That was a blind copy paste. I will remove the extra sdcard.
