Subject: [PATCH v2 0/2] remoteproc: xlnx: Add attach detach ops and sram support

Attach detach ops are needed to connect to remote processor that is
running before remoteproc driver is probed. Implement remoteproc
framework ops that enables such use case on AMD-Xilinx platforms.

Remote processor can also use On Chip sram Memory (OCM) for various
purpose. For example, for fast code execution or data access compare
to DDR memory. Such sram region is made available to remoteproc nodes
via "sram" property. Add support in driver to parse and use OCM memory
via sram property.

Changes in v2:
  - Fix following sparse warnings

drivers/remoteproc/xlnx_r5_remoteproc.c:827:21: sparse:    expected struct rsc_tbl_data *rsc_data_va
drivers/remoteproc/xlnx_r5_remoteproc.c:844:18: sparse:    expected struct resource_table *rsc_addr
drivers/remoteproc/xlnx_r5_remoteproc.c:898:24: sparse:    expected void volatile [noderef] __iomem *addr
drivers/remoteproc/xlnx_r5_remoteproc.c:995:26: sparse: warning: Using plain integer as NULL pointer

Tanmay Shah (2):
  drivers: remoteproc: xlnx: add attach detach support
  drivers: remoteproc: xlnx: add sram support
