/* 05-00-0428 - "Lost/Corrupted Write to L2 Memory Following Speculative Read
 * by Core B from L2 Memory"
 *
 * This issue occurs only when the accesses are performed by core B of a BF561.
 *
 * When a write to internal L2 memory follows a speculative read from internal
 * L2 memory, the L2 write may be lost or corrupted. For this anomaly to occur,
 * the speculative read must be caused by a read in the shadow of a branch. The
 * accesses do not have to be consecutive accesses. In other words, the problem
 * can occur even if there are multiple instructions between the speculative
 * read and the write, as shown in the following example:
 *
 *   R1 = 1; R2 = 1;
 *   CC = R1 == R2;
 *   IF CC JUMP X;  // Always true...
 *   R0 = [P0];     // If any of these three loads accesses L2 memory from Core
 *   R1 = [P1];     // B, speculative execution in the pipeline causes the
 *   R2 = [P2];     // anomaly trigger condition.
 *   X:
 *   ...            // Any number of instructions...
 *   [P0] = R0;  // This write can be corrupted or lost.
 *
 * The issue does not occur if the speculative read access is caused by an
 * interrupt or exception.
 *
 * The workaround required depends upon the conditional branch instruction.
 * If the evaluated condition is true and the branch is predicted, then the
 * workaround is to ensure that the target instruction is not be a load
 * instruction, for example:
 *
 *   IF CC JUMP X (BP);
 *   ...
 *   X: <load that might be from L2 memory>
 *
 * If the evaluated condition is false and the branch is not predicted, then
 * the workaround is to make sure that none of the three instructions that
 * are executed after the conditional JUMP are load instructions, for example:
 *
 *   IF CC JUMP ...;
 *   <load that might be from L2 memory>
 *   <load that might be from L2 memory>
 *   <load that might be from L2 memory>
 *
 * This problem impacts:
 * BF561 - rev 0.4,0.5
