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