soc: fsl: qbman: add APIs to retrieve the probing status

2018-09-27T20:43:35Z

Add a couple of new APIs to check the probing status of qman and bman: 'int bman_is_probed()' and 'int qman_is_probed()'. They return the following values. * 1 if qman/bman were probed correctly * 0 if qman/bman were not yet probed * -1 if probing of qman/bman failed Drivers that use qman/bman driver services are required to use these APIs before calling any functions exported by qman or bman drivers or otherwise they will crash the kernel. The APIs will be used in the following couple of qbman portal patches and later in the series in the dpaa1 ethernet driver. Signed-off-by: Laurentiu Tudor Signed-off-by: Li Yang

This driver enables the Freescale DPAA 1.x Buffer Manager block. BMan is a hardware accelerator that manages buffer pools. It allows CPUs and other accelerators connected to the SoC datapath to acquire and release buffers during data processing.
