Hi Linus,
please pull these 3 patches to your tree. They are adding architecture support
for error injection which can be done only via local memory (BRAM) with enabling
path for recovery after reset. These patches targets Triple Modular Redundacy
(TMR) configuration where 3 Microblazes are running in parallel with monitoring
logic.
When an error happens (or is injected) system goes to break handler with full
CPU reset and system recovery back to origin context.
More information can be found here:

Thanks,
Michal
