5d42a685 - m68k: Move Sun 3 into a top-level platform option

Wed, 30 Oct 2024 19:56:13 +0000

m68k: Move Sun 3 into a top-level platform optionIt is possible to select an m68k MMU build but not actually enable anyof the three MMU options, which then results in a build failure: arch/m68k/include/asm/page.h:10:25: error: 'CONFIG_PAGE_SHIFT' undeclared here (not in a function); did you mean 'CONFIG_LOG_BUF_SHIFT'?Change the Kconfig selection to ensure that exactly one of the threeoptions is always enabled whenever an MMU-enabled kernel is built, butmoving CONFIG_SUN3 into a top-level option next to M68KCLASSIC andCOLDFIRE.All defconfig files should keep working without changes, butalldefconfig now builds support for the classic MMU.Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202408032138.P7sBvIns-lkp@intel.com/Signed-off-by: Arnd Bergmann Acked-by: Greg Ungerer Reviewed-by: Geert Uytterhoeven Link: https://lore.kernel.org/20241030195638.22542-1-arnd@kernel.orgSigned-off-by: Geert Uytterhoeven List of files: /linux-6.15/arch/m68k/Kconfig.machine

0100f67c - m68knommu: improve config ROM setting defaults

Wed, 13 Sep 2023 11:58:22 +0000

m68knommu: improve config ROM setting defaultsThe ROM region configuration settings used on some nommu m68k systems(historically mostly 68328 (Dragonball) CPUs) default to an addressof 0. That can easily clash with default RAM address settings whichalso default to 0. Of course that is invalid and those ranges overlap,but if you make no value selection that is what you end up with. Thosedefault values produce a valid configuration but will fail compilationlike this: m68k-linux-ld: section .rodata VMA [0000000000001000,0000000000262227] overlaps section .text VMA [0000000000000400,0000000000455e7f]Looking at the platforms that use the ROM region configuration settingsit is clear that we can choose much better defaults than 0. By far themost common ROM region settings are these: CONFIG_ROMVEC=0x10c10000 CONFIG_ROMSTART=0x10c10400So lets make these the default values.It is still possible to configure overlapping ROM and RAM regions, butat least the default selections are now valid.Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202305301407.z33zOjcG-lkp@intel.com/Signed-off-by: Greg Ungerer List of files: /linux-6.15/arch/m68k/Kconfig.machine
