board: qemu: m68k: Create virtio mmio instances

2026-05-22T22:47:54Z

So that you can use virtio network, block etc create the virtio mmio instances. There are 128 of these even if they are not all used, a single mmio base value is passed via bootinfo.

m68k: Fix writew(), writel(), readw(), readl() endianness for classic m68k

2026-05-22T22:47:54Z

In Linux these are meant to read a little-endian value and swap to the CPU endian. In u-boot for m68k this is currently broken and prevents virtio-mmio from functioning. This change is only for classic m68k. Coldfire has read big-endian, no swap for these in u-boot and Linux and existing drivers probably depend on this.

m68k: set proper u-boot image size for initial boot

2026-05-04T20:19:49Z

There is a value of 256K hardcoded as u-boot image size. This produce bank tty as soon as the image size grows over the limit. Fix it by using value preset by CONFIG_SYS_MONITOR_LEN. Signed-off-by: Angelo Dureghello

m68k: mcf5441x: create stub to use imx drivers

2026-05-04T20:19:49Z

Some NXP imx hardware ip module as the esdhc controller are exactly the same in some new ColdFire cpus. For the specific case, mcf5441x needs to use the existing fsl_esdhc_imx.c driver for the esdhc device. Create a stub to be able to use NXP "imx" serie drivers as the fsl_esdhc_imx in the ColdFire architecture. Signed-off-by: Angelo Dureghello

Merge patch series "bootm: Clean up arch-specific, pre-OS clean-up"

2026-03-19T00:36:50Z

Simon Glass says: Each arch does something slightly different before booting the OS. Some archs even do different things depending on the CPU type. It is quite hard to know what actually happens in the final milliseconds before the OS boot. This series attempts to start cleaning up U-Boot in this area. The basic intent is to create a new bootm_final() function which can be called by all archs. It provides some flags for a couple of necessary variations but otherwise it is generic. All architectures are converted over to use this new function. board_quiesce_devices() is moved into bootm_final() so that all archs benefit from it. This series fixes a bug in device_remove() is fixed where removing a parent with specialised flags (e.g. DM_REMOVE_ACTIVE_ALL) could leave children activated, since they do not match the flags. This fixes is needed to avoid bootm_final() causing test failures on sandbox. Future work could take this a little further: - Convert EFI loader to use the same function - Improve comments for cleanup_before_linux() across architectures - Support fake-run tracing on all archs Link: https://lore.kernel.org/r/20260306023638.2678886-1-sjg@chromium.org
