FWIW, I have the feeling this has a slight influence on boot reliability on
two of my boards:
  - r8a7740/armadillo, which is known to suffer from a cache-related bug in
    its bootloader, seems to have a higher change of booting successfully on
    cold boot,
  - sh73a0/kzm9g, which has known cache-issues with secondary CPU boot up,
    seems to have a lower chance of booting successfully.

No time to spend all week turning this into a statistical significant test
project... The reset button is my friend...

Damn it, you sent this right after I merged and pushed out this change in
my for-arm-soc branch, and was just about to send it to the arm-soc people.
What excellent timing you have. :)

What happens on the kzm9g if you revert the mach-shmobile changes?

For armadillo, do you use the decompressor?  That should be doing all the
cache cleaning already, prior to the kernel being entered.
