[U-Boot] ARM: 743626—An imprecise external abort, received while the processor enters WFI, may cause a processor deadlock

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.

your first problem.

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