This patch series adds support for Triple Modular Redundancy Subsystem,
Triple Modular Redundancy (TMR) Microblaze solution provides soft error
detection, correction and recovery for Microblaze cores in the system.
The Xilinx/AMD Triple Modular Redundancy (TMR) solution in Vivado provides
all the necessary building blocks to implement a redundant triplicated
MicroBlaze subsystem. This processing subsystem is fault-tolerant and
continues to operate nominally after encountering an error. Together
with the capability to detect and recover from errors, the implementation
ensures the reliability of the entire subsystem, for more details about
IP please refer PG268[1].
