ARM Trusted Firmware exports a series of build flags which control the

errata workarounds that are applied to each CPU by the reset handler. The
|

errata details can be found in the CPU specific errata documents published

by ARM. The errata workarounds are implemented for a particular revision
|

or a set of processor revisions. This is checked by reset handler at runtime.
