Roy Pledge	6ea4c0fe45	soc/fsl/qbman: Update device tree with reserved memory ... When using the reserved memory node in the device tree there are two options - dynamic or static. If a dynamic allocation was selected (where the kernel selects the address for the allocation) convert it to a static allocation by inserting the reg property. This will ensure the same memory is reused after a kexec() Signed-off-by: Roy Pledge <roy.pledge@nxp.com> Signed-off-by: Li Yang <leoyang.li@nxp.com>	2019-08-15 16:42:00 -05:00
Roy Pledge	97777078d6	soc/fsl/qbman: Rework QBMan private memory setup ... Rework QBMan private memory setup so that the areas are not zeroed if the device was previously initialized If the QMan private memory was already initialized skip the PFDR initialization.

Luis Chamberlain	750afb08ca	cross-tree: phase out dma_zalloc_coherent() ... We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out.

Roy Pledge	42d0349784	soc/fsl/qbman: Add common routine for QBMan private allocations ... The QBMan device uses several memory regions to manage frame queues and buffers. Add a common routine for extracting and initializing these reserved memory areas.
