[Qemu-arm] [PATCH v3 00/30] Initial i.MX7 support

[Andrey Smirnov]

Hi everyone,

This v3 of the patch series containing the work that I've done in
order to enable support for i.MX7 emulation in QEMU.

As the one before last commit in the series states the supported i.MX7
features are:

    * up to 2 Cortex A9 cores (SMP works with PSCI)
    * A7 MPCORE (identical to A15 MPCORE)
    * 4 GPTs modules
    * 7 GPIO controllers
    * 2 IOMUXC controllers
    * 1 CCM module
    * 1 SVNS module
    * 1 SRC module
    * 1 GPCv2 controller
    * 4 eCSPI controllers
    * 4 I2C controllers
    * 7 i.MX UART controllers
    * 2 FlexCAN controllers
    * 2 Ethernet controllers (FEC)
    * 3 SD controllers (USDHC)
    * 4 WDT modules
    * 1 SDMA module
    * 1 GPR module
    * 2 USBMISC modules
    * 2 ADC modules
    * 1 PCIe controller
    * 3 USB controllers
    * 1 LCD controller
    * 1 ARMv7 DAP IP block

Feedback is welcome!

Changes since [v2]:

    - Added stubs for more blocks that were causing memory
      transactions when booting Linux guest as were revealed by
      additional testing of the patchest

    - Added proper USB emulation code, so now it should be possible to
      emulated guest's USB bus

Changes since [v1]:

    - Patchset no longer relies on "ignore_memory_transaction_failures = false"
      for its functionality

    - As a consequnce of implementing the above a number of patches
      implementing dummy IP block emulation as well as PCIe emulation
      patches that I alluded to in [v1] are now included in this patch
      series

    - "has_el3" property is no longer being set to "false" as a part
      of intialization of A7 CPU. I couldn't reproduce the issues that
      I thought I was having, so I just dropped that code.

    - A number of smaller feedback items from Peter and other has been
      incorporated into the patches.


Peter, I didn't hear anything from you about the code of
mcimx7d_add_psci_node(), as discussed here:

https://www.mail-archive.com/address@hidden/msg486874.html

so I kept the original code intact. As I mentioned before, my goal was
to be able to boot into vanilla Linux kerenel and have working SMP
without needing to use a PSCI implementing bootloader. If that is
something that new board code shouldn't do, please let me know.

Thanks,
Andrey Smirnov
