we have to develop own driver software for ethernet communication using a QorIQ T1042 processor. Therefore, we read the appropriate DPAA documentation (reference manual etc.). But now we are a little bit lost in building our own DPAA driver (FMan, QMan, ...). We are using the NXP T1042D4RDB evaluation board as plattform. For this purpose we downloaded the "Source" package of the Yocto Linux SDK (V2.0). Because we are not very familar with the Linux code sources, please can you tell us, where in the Yocto linux sources we can find the core drivers for the DPAA hardware (accessing the FMan, QMan, Portals, ...)?
