[RFC 4/7] soc/qman: add helper functions needed by caam/qi driver
Horia Geantă
horia.geanta at nxp.com
Fri Mar 3 06:52:10 PST 2017
Add helper functions, macros, #defines for accessing / enabling
qman functionality from caam/qi driver, such that this driver
is not aware of the need for data conversion to big endian.
qman is updated to use these helpers internally.
