The filesystem types can benefit from this script to prevent common mistakes when submitting patches. In order to accomplish this: Do not ignore anymore files from the fs/ directory. Ignore fs/common.mk as it declares a package infra and not a package itself. Register the ROOTFS_ as a valid prefix for variables. Ignore these symbols: - PACKAGES_PERMISSIONS_TABLE: defined either by packages through pkg-generic or by filesystem types, used by fs/common.mk; - SUMTOOL: defined by package mtd, used by filesystem jffs2; - TARGETS_ROOTFS: defined by filesystem types, used in the main Makefile. Keep using loose checks that warn about common mistakes while keep the code simple. As a consequence the check functions do not differentiate between packages and filesystems so the symbol PACKAGE_UBI would not generate a warning for the ubi filesystem neither the symbol ROOTFS_MTD would generate a warning for the mtd package. But those kind of mistakes are not common and are obvious in the code review, unlike typos i.e. ROOTFS_UBl or PACKAGE_MID that would be hard to see in the code review.

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
