Indeed, my code currently doesn't setup the TLB.
So you're using the initial mapping that the U-Boot spin table code creates?
It looks like that entry is missing MAS2_M. This needs to be fixed.
The secondary IMA that U-Boot creates also needs to begin at effective address zero to be ePAPR-compliant.
Yes, U-Boot is still running on core 0. I'm looking for a non-preemptive environment to run some benchmarks,
U-Boot is a bootloader, not a benchmarking environment. It is strongly recommended that you not leave U-Boot running on any CPU (including spin table code) if you're running benchmarks. For example, U-Boot will be continuously polling the serial port, which includes sync instructions that get broadcast to other CPUs.
Is there a way to link my standalone application with the functions in U-Boot that manage the TLB, caches, etc.?
You could in theory create a custom U-Boot instance that runs in this way -- but again, U-Boot is a bootloader and is not ideally suited to this task. What hardware init are you referring to?
