[ARM] Marvell Feroceon CPU core support
The Feroceon is a family of independent ARMv5TE compliant CPU core
implementations, supporting a variable depth pipeline and out-of-order
execution. The Feroceon is configurable with VFP support, and the
later models in the series are superscalar with up to two instructions
per clock cycle.
This patch adds the initial low-level cache/TLB handling for this core.
