The handling of BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG is currently not doing a proper job: it is selecting ppc64le_defconfig if BR2_powerpc64le, and using the default of "defconfig" for everything else. However: - Since upstream commit 22f17b02f88b48c01d3ac38d40d2b0b695ab2d10, which landed in Linux 6.8, the default defconfig is ppc64le_defconfig and no longer ppc64_defconfig. This means that despite the condition in linux.mk, we are in fact now always building ppc64le_defconfig. - It doesn't handle the 32-bit case, as a 64-bit defconfig gets used by default. This causes build failures in the autobuilders. To fix this we explicitly handle BR2_powerpc64le, BR2_powerpc64 and BR2_powerpc, and use appropriate defconfigs for each case.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
