[v5] Adding comprehensive support for i.MX8MM EVK board

[PATCHv5 00/15] Adding comprehensive support for i.MX8MM EVK board

Posted by Gaurav Sharma 2 weeks, 1 day ago

Changes in v5:
- Fixed SoC object reference counting by using object_new_with_props()
  instead of object_new() + object_property_add_child()
- Merged imx8mm-evk.rst documentation into imx8mp-evk.rst to avoid
  duplication and updated the title accordingly
- Added on-chip RAM (OCRAM) support to match iMX8MP dev

Changes in v4:
- Update Maintainers file
- Re-used iMX8MP CCM and Analog IP for iMX8MM by introducing a variant
  specific property
- Split up the patch that enabled CCM and Analog in the previous
  revision. Now we have 3 patches to enable CCM and Analog in iMX8MM
- Updated copyrights
- Removed '|| KVM' from hw/arm/Kconfig to prevent 'make check' failures

Changes in v3:
- Minor documentation change - Added KVM Acceleration section in docs/system/arm/imx8mm-evk.rst

Changes in v2:
- Fixed the DTB offset in functional testing script test_imx8mm_evk.py
  and preserved alphabetical order of machine names in tests/functional/aarch64/meson.build
- Fixed a typo and updated the documentation
- Modified structures type to static const in fsl-imx8mm.c wherever
  applicable.
- Added CSI and DSI nodes to the nodes_to_remove list in imx8mm-evk.c. This
  is needed because the default DTB in the iMX LF BSP images have CSI
  and DSI enabled. Developers/Hobbyists using these BSP images will
  observe CSI and DSI crash logs on the console since these are unimplemented.
  With this change, both debian and iMX LF images will boot up without any issues.

Changes in v1:

This patch series adds support for the NXP i.MX8MM EVK (Evaluation Kit)
board to QEMU, enabling emulation of this ARM Cortex-A53 based development
platform.

The series includes:

1. Core peripheral support (CCM clock controller, Analog module)
2. GPT(General Purpose Timer) and WDT(Watchdog Timer) Emulation support
3. GPIO,I2C,SPI,USDHC and USB Emulation support
4. PCIe and ENET Controller Emulation support
5. Documentation and functional test included

Key features ported:
- Basic boot support with Linux
- UART console for serial communication
- Interrupt handling
- Clock and power management infrastructure

Testing:
- Linux kernel boots to console

Checkpatch raises several errors (you may ignore its warnings). Reproduce in the QEMU root src dir with the following command:

  ./scripts/checkpatch.pl --branch origin/master..
