[PATCH v8 00/18] Add support for FDMA DMA controller and slim core rproc found on STi chipsets
...subsystem implements a new mechanism for
firmware on late mounted root filesystems, we can migrate this driver over to use it
at that point.
v8 actions some review feedback from Bjorn to the slim rproc driver, and also includes
a patch which fixes a recursive Kconfig error which is triggered when st_fdma selects
slim_rproc driver. The series has also been rebased on v4.8-rc3.
regards,
Peter.
Changes since v7:
- Rebase on v4.8-rc3 (Peter)
- Double check that len is <= mem[i].size (Bjorn)
- Remove if (!fw) checks (Bjorn)
- Omit reference from fw_ops struct (Bjorn)
- Call rproc_del() before...
