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: 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 "m68k: Add support for QEMU virt machine"

2026-02-02T20:25:48Z

Kuan-Wei Chiu says: Add support for the QEMU 'virt' machine on the m68k architecture. The QEMU virt machine models a generic system utilizing Goldfish virtual peripherals and is capable of emulating various classic 68k CPUs. Currently, U-Boot's m68k architecture support focuses on ColdFire variants. This series expands support to include the classic M680x0 architecture, implementing the necessary exception vectors, startup code, and a bootinfo parser compatible with the QEMU interface. Drivers for Goldfish peripherals (TTY, Timer, RTC) and the QEMU Virtual System Controller (sysreset) are also added to enable serial console, timekeeping, and system reset functionality. The implementation has been verified on QEMU targeting the M68040 CPU, confirming successful hardware initialization and boot to the U-Boot command shell. Additionally, the CI configuration was verified locally using gitlab-ci-local "qemu_m68k_virt test.py", resulting in PASS qemu_m68k_virt test.py.

board: Add QEMU m68k virt board support

2026-02-02T20:24:41Z

Add support for the QEMU 'virt' machine on the m68k architecture. This board emulates a generic machine based on the Motorola 68040 CPU equipped with Goldfish virtual peripherals. Introduce the necessary board configuration and initialization infrastructure. The implementation includes logic to parse the QEMU bootinfo interface, enabling dynamic detection of system RAM size to adapt to the virtual machine's configuration. Enable the Goldfish TTY driver for serial console output. Additionally, enable Goldfish RTC and timer drivers to support real-time clock functionality and nanosecond-resolution delays. Include comprehensive documentation covering build instructions and usage examples. Signed-off-by: Kuan-Wei Chiu Tested-by: Daniel Palmer Reviewed-by: Simon Glass

m68k: Add support for M68040 CPU

2026-02-02T20:24:41Z

Add support for the Motorola 68040 architecture. Currently, m68k support in U-Boot is primarily focused on ColdFire variants. Introduce the necessary infrastructure to support the classic M680x0 series, specifically targeting the M68040 as emulated by QEMU. The implementation includes exception vectors, early startup code, and minimal CPU initialization and relocation stubs. It also defines the standard m68k boot information structure used for passing hardware information to the operating system. To ensure compatibility, ColdFire- specific library objects such as cache and interrupt handling are excluded from the build when M68040 is selected. Additionally, apply a specific workaround during the early memory reservation stage. Use a manual loop to clear global data instead of the standard memset() function, as utilizing memset() at this point was observed to cause a hang on the QEMU platform.

board: nxp: Rename board directory from board/freescale to board/nxp

2026-01-28T06:26:50Z

This patch renames the board directory from board/freescale to board/nxp because NXP now provides Board Support Packages (BSPs) and tools for the former Freescale i.MX and other i.MX products. All relevant references have been updated accordingly. This change does not affect functionality. Signed-off-by: Alice Guo Reviewed-by: Fabio Estevam

arch: m68k: Implement relocation

2023-09-06T11:28:58Z

Implement relocation for M68K. Perform all the updates in start.S relocate_code in assemby, since it is a simple matter of traversing the dynsym table and adding relocation offset - MONITOR_BASE to all the items in that table. The necessity to deal with MONITOR_BASE is a specific of M68K, where the ELF entry point is at offset 0x400, which is the MONITOR_BASE, while TEXT_BASE is at offset 0 . This also removes the one last user of NEEDS_MANUAL_RELOC, so that could be finally cleaned up . Reviewed-by: Simon Glass Signed-off-by: Marek Vasut
