This series fixes various issues in i.MX device emulation, cleans up i.MX Kconfig handling, and improves some code. Functional console tests for the remaining i.MX boards are added where images are publicly available, except for imx6ul which is taken care of in a different series [1]. Fixes which appear safe for backporting are cc'd to qemu-stable.
The series is structured as follows: Patches 1-5 fix some issues and are mostly marked for backporting. Patch 4 is a follow-up on patches 1-3 and should not be backported since it breaks migration. Patches 6-11 add and improve functional tests for i.MX devices. While at it, saner defaults for the amount of RAM and number of CPUs are established. Patches 12-16 turn the remaining i.MX SoC device models into SySBus devices which fixes their reset behavior. Patches 17-30 are Kconfig cleanups where CONFIG_IMX gets split into dedicated config items. The last commit just fixes some typos in the code. Changes in v3: * Add dedicated patch fixing write one once WCR bits, cc'd to qemu-stable (Bin) Done as yet another patch to tell the issues apart. * Add and fix some commit messages (Bin) * Add functional tests to 'tests_arm_system_thorough' (Bin) * Fix typo in functional tests for mcimx7d-sabre machine (Bin) * Use sysbus_realize() rather than sysbus_realize_and_unref() in case of embedded SoC struct (Bin) * Pick up R-b tags Changes in v2: * Remove patch adding `mc->ignore_memory_transaction_failures = true;` (Peter) * Rework wdt_imx2 patches (Peter) * Remove all but "hw/misc/Kconfig: Remove redundant USB_EHCI_SYSBUS from config IMX" already queued by Phil. The preserved patch is required to remove all dependencies from CONFIG_IMX such that it can be removed. * Pick up R-b tags * Rebase onto latest master [1] https://lore.kernel.org/qemu-devel/20261004090500.3082641-1-bin.
