In commit3e5926555b("package/{mesa3d, mesa3d-headers}: bump version to 17.1.2"), the dependency of VC4 on BR2_arm was changed to BR2_ARM_CPU_HAS_NEON, which the reasoning that upstream commit https://cgit.freedesktop.org/mesa/mesa/commit/?h=17.1&id=4d30024238efa829cabc72c1601beeee18c3dbf2 made NEON mandatory. However, this commit (including its commit log) clearly shows that there is compile-time detection on whether you're using ARMv6 or ARMv7, and simply says there is no runtime detection for that (which usually isn't very important in the context of Buildroot). So, the VC4 driver can be used on ARMv6 RaspberryPis. Therefore, this commit reverts to the BR2_arm dependency. Note: while there are some ARMv7 without NEONs, all ARMv7 RaspberryPi platforms do have NEON, so the compile-time checks done in the VC4 driver are good enough.

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 Freenode IRC.
