Hello,

I added workarounds for Cortex-A9 Errata 794072 and 845369 to the RTEMS 
5 and master branches:

https://devel.rtems.org/ticket/4114

https://devel.rtems.org/ticket/4115

They are only relevant in SMP configurations. Some bootloader already 
enable these workarounds. The hardware bug in Errata 845369 can lead to 
data corruption and we noticed system crashes due to it which are hard 
to debug.
