I guess these are the same blocks as for DPAA2? They are in drivers/bus/fslmc/ Why introducing yet another bus driver? The fslmc one was supposed to cover any Freescale (NXP (Qualcomm)) SoC. > 2. DPAA Mempool (drivers/mempool/dpaa) > BMan, or Buffer Manager, block of DPAA features a hardware offloaded > mempool. These patches add support for a driver to manage the BMan > block.

I think everybody was scared about reviewing it. Why you did not split it?
