I'll keep debugging it here, did reverting this commit, help with the resets? http://git.denx.de/?p=u-boot.git;a=commit;h=28e5ac2d974547bde0c72aa0c1d66fd2...
Tried reverting it and still see the data-aborts.
I am also testing on my mx53loco board with the mc34708 pmic and I see that it hangs on boot about 10% of the attempts: U-Boot 2013.01-rc2-00172-gf8cfcf1-dirty (Dec 26 2012 - 15:15:27)

This did not happen prior to commit c73368150 (pmic: Extend PMIC framework to support multiple instances of PMIC devices).
Okay, now we are on the same page, upgraded to: "arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.7-2012.12-20121214 - Linaro GCC 2012.12) 4.7.3 20121205 (prerelease)"..
With your Dialog patch, it is properly setting 1Ghz, and just keeps rebooting.. :)
