[v3,00/10] Xilinx Versal's PMC SLCR and OSPI support

Message

Hi,

This series attempts to add support for Xilinx Versal's PMC SLCR
(system-level control registers) and OSPI flash memory controller to
Xilinx Versal virt machine.

The series start with adding a model of Versal's PMC SLCR and connecting
the model to the Versal virt machine. The series then adds a couple of
headers into the xlnx_csu_dma.h needed for building and reusing it later
with the OSPI. The series thereafter introduces a DMA control interface
and implements the interface in the xlnx_csu_dma for being able to reuse
and control the DMA with the OSPI controller. Thereafter a model of
Versal's OSPI controller is added and connected to the Versal virt
machine. The series then ends with adding initial support for the Micron
Xccelera mt35xu01g flash and flashes of this type are connected to the
OSPI in the Versal virt machine.

Best regards,
Francisco Iglesias

Changelog:
v2 -> v3
  * Correct and also include hw/sysbus.h and hw/register.h into
    xlnx_csu_dma.h (patch: "include/hw/dma/xlnx_csu_dma: Add in missing
    includes in the header")

v1 -> v2
  * Correct the reset in the PMC SLCR model
  * Create a sub structure for the OSPI in the Versal structure (in patch:
    "hw/arm/xlnx-versal: Connect the OSPI flash memory controller model")
  * Change to use 'drive_get' instead of 'drive_get_next' (in patch:
    "hw/arm/xlnx-versal-virt: Connect mt35xu01g flashes to the OSPI")
  * Add a maintainers patch and list myself as maintainer for the OSPI
    controller
