207 The reconstruction of this module was more of a translation of logic
208 from disassembly to C than adaptation of source from other versions,
209 hence it is not a bit-for-bit match or even close. However, the logic
210 has been carefully verified and confirmed to match the original; see
211 chipsetsw/layer1/tpu_drivers/source0/tpudrv12.notes for the details.
