// Waive some width mismatch warnings in keymgr*.sv that come from addressing an
// array by literal elements of an enum that has an extra entry. For example,
// keymgr_ops_e contains 4 actual operations plus an "OpDisable" entry, meaning
// that its elements are represented by $clog2(5) = 3 bits. However, we use its
// literal values to index into things like the error_o array, which just has an
// entry for each of the 4 real operations. Because $clog2(4) = 2, Verilator
// expects to address it with a 2-bit index and generates a warning.
