So far, all ARM cores were selecting BR2_ARCH_HAS_MMU_OPTIONAL, except no-MMU cores which were selecting nothing. In practice, MMU-capable ARM cores are always used with their MMU enabled, so it doesn't make sense to support the use case of not using the MMU on such cores. Consequently, to simplify things, we group the MMU handling in the BR2_ARM_CPU_ARM* options: BR2_ARM_CPU_ARMV4, BR2_ARM_CPU_ARMV5, BR2_ARM_CPU_ARMV6, BR2_ARM_CPU_ARMV7A, BR2_ARM_CPU_ARMV8A all select BR2_ARCH_HAS_MMU_MANDATORY, while BR2_ARM_CPU_ARMV7M continues to select nothing, indicating that there is no MMU available at all.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
