More and more packages being tested by the test infra, e.g. syslog-ng, need entropy at startup, usually reading from /dev/random. Some test cases can also depend on a kernel version newer than the builtin ones already provided by the test infra: - 3.11.0 for armv5; - 4.0.0 for armv7. Add a new builtin kernel to be used by such test cases. Add it for armv5 so most test cases that switch to use this kernel can keep using BASIC_TOOLCHAIN_CONFIG. Use the same kernel version and kernel config as qemu_arm_versatile plus HW_RANDOM_VIRTIO for VirtIORNG to be usable. Copy the actual binary file from the syslog-ng runtime test at current master @29e1cb8884. Since there is already a 'kernel-versatile' file on autobuild.buildroot.net and we must keep it with this name for reproducibility purposes, create a simple naming convention for newer builtin kernel images and dtb files: kernel-<defconfig>-<kernel_series_version> <dtb_name>-<kernel_series_version>.dtb Pass '-device virtio-rng-pci' to qemu when this kernel is used.

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