So far, spin-table has not been defined for 32-bit, and the code below, while mostly a copy of the 64-bit code, is somewhat different. If you want a common enable method, I would strongly advise that you use PSCI, which is well-defined for both 32-bit and 64-bit. There are a number of problems with spin-table, and I would not recommend extending it to 32-bit ARM. Thanks, Mark.
