After the kernel boots, seeing instability with frequent reboots on LS1043ARDB on idle. Need to check reset status register and see if this is a known issue on any QorIQ platform and what is the root cause if open defect or fixed.


How do we read the Reset Request Status Register (DCFG_CCSR_RSTRQSR1)?  Need the section of kernel code where reads should be done and an example needed. 


See section 12.3.14 Reset Request Status Register (DCFG_CCSR_RSTRQSR1) in chapter 12 Device Configuration and Pin Control. QorIQ LS1043A Reference Manual rev. 1 8/16. See LS1021A Reset Reason
