   9 // Contains all of the Cortex-A57 specific SchedWriteRes types. The approach
  10 // below is to define a generic SchedWriteRes for every combination of
  11 // latency and microOps. The naming conventions is to use a prefix, one field
  12 // for latency, and one or more microOp count/type designators.
  13 //   Prefix: A57Write
  14 //   Latency: #cyc
  15 //   MicroOp Count/Types: #(B|I|M|L|S|X|W|V)
  16 //
  17 // e.g. A57Write_6cyc_1I_6S_4V means the total latency is 6 and there are
  18 //      11 micro-ops to be issued as follows: one to I pipe, six to S pipes and
  19 //      four to V pipes.
