Please provide the patch or the fix for this issue. Im very new to the Memory Management. It would be very helpful for me if any one provides more Information. Some Workaround has been mentioned in the freescale errata document, but it looks like too high level and im not understanding it completely.

http://catb.org/esr/faqs/smart-questions.html#beprecise will solve your first problem.

And please check if you have at least a single wfi instruction in the mainline u-boot for your board.
