New Revision: 291008
URL: https://svnweb.freebsd.org/changeset/base/291008
Log:
Add support for new LAW registers in QorIQ SoCs.
QorIQ SoCs (e5500 core, P5 family) have 2 BARs for local access windows, while
MPC85XX, and P1/P2 families use only a single BAR register.
This also adds the QORIQ_DPAA option, mutually exclusive to MPC85XX, to handle
this difference.
