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?
