2026-05-04m68k: mcf5441x: create stub to use imx driversAngelo Dureghello
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 <[email protected]>
2026-02-02Merge patch series "m68k: Add support for QEMU virt machine"Tom Rini
Kuan-Wei Chiu <[email protected]> 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.

2026-02-02board: Add QEMU m68k virt board supportKuan-Wei Chiu
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.

2026-02-02m68k: Add support for M68040 CPUKuan-Wei Chiu
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.

2023-09-06arch: m68k: Implement relocationMarek Vasut
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 <[email protected]> Signed-off-by: Marek Vasut <[email protected]>

2022-06-24microblaze: Add support for run time relocationMichal Simek
Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing issues with function pointer arrays which need to be updated manually after relocation. Building code with -fPIC and linking with -pic will remove this limitation and there is no longer need to run manual update. By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC code will be compiled for full relocation. The patch does couple of things which are connected to each other. - Define STATIC_RELA dependency to call relocate-rela to fill sections. - REMAKE_ELF was already enabled but u-boot file can't be used because sections are empty. relocate-rela will fill them and output file is u-boot.elf which should be used. - Add support for full relocation (u-boot.elf) - Add support for early relocation when u-boot.bin is loaded to different address then CONFIG_SYS_TEXT_BASE - Add rela.dyn and dynsym sections Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original size (550kB to 608kB).

2021-12-27Finish converting CONFIG_WATCHDOG, HW_WATCHDOG and WDT to KconfigTom Rini
Because of how these symbols work, and the remaining board config.h file uses, we need to do these at the same time. In some cases we just get to move rather directly to the defconfigs. A few cases require manual intervention. For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the target, given how it's implemented. For the cases of m53menlo, dh_imx6, display5, and display5_factory we disable SPL watchdog support as the particular combination of options they want would require either more symbols or enabling SPL_DM.

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.
