[PATCH v5 00/12] Xilinx Versal's PMC SLCR and OSPI support |

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:
v4 -> v5
* Use named GPIOs for "sd-emmc-sel", "qspi-ospi-mux-sel", "ospi-mux-sel"
in the PMC SLCR model
* Add a QEMU interface comment for the PMC SLCR model.
* Switch to use OBJECT_DECLARE_SIMPLE_TYPE in both "xlnx-versal-ospi.h"
and "xlnx-versal-pmc-iou-slcr.h"
* Create a new patch 'or'ing the interrupts from the BBRAM and RTC model
* 'Or' the interrupt from the PMC SLCR with the BBRAM and RTC interrupt
inside 'xlnx-versal.c'
* Connect other not yet implemented PMC SLCR GPIOs to unimplemented messages
* Reworked and simplified the DMA control interface by removing the
notifier and refill mechanism
* Corrected various typos and grammatical errors in the DMA control
interface documentation and comments
* Updated the DMA control interface documentation to describe the new
simplified implementation
* Use ldl_le_p and ldq_le_p in the OSPI model (and remove the OSPIRdData
union). Also assert in the locations that we are not overruning the
new bytes buffer.
* Correct the single_cs function in the OSPI model (both comment and output)
* Correct a typo in a comment inside ospi_do_indirect_write
(s/boundery/boundary/)
* Remove an unecesary assert in the OSPI model
* Add a QEMU interface comment for the OSPI model.
* Rename the OSPI irq in 'xlnx-versal.c' to include 'orgate' in the name for
clarifying
v3 -> v4
* Correct indentation (patch: "hw/arm/xlnx-versal: Connect Versal's PMC
SLCR")
* Rename to include "If" in names related to the DMA control interface
* In dma-ctrl-if.h:
- Don't include qemu-common.h
- Use DECLARE_CLASS_CHECKERS dma-ctrl.h
* Add a docs/devel documentation patch for the DMA control interface
* Improve git messages on the dma-ctrl-if patches
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
