BootROM will not perform a full 128-KB CRC self-check of the ROM contents even if the corresponding eFuse bit setting is programmed in the PS.
|Impact:||Trivial. If there is a post-production bit failure in the ROM, then the behavior will be undefined instead of shutting down.|
|Work-around:||Insert a DMB or DSB instruction between the write to Strongly Ordered memory region and the LDREX instruction.|
|Configurations Affected:||Systems that use the CPUs.|
|Device Revision(s) Affected:||Refer to (Xilinx Answer 47916) - Zynq-7000 SoC Silicon Revision Differences.|
Note: the ROM is tested and screened for manufacturing defects during production.
