Although we currently don't have a .hash file for linux-headers, there already are exclusions for the BR2_KERNEL_HEADERS_AS_KERNEL case (copied from linux.mk). However, there is no exclusion for the BR2_KERNEL_HEADERS_VERSION case. For the BR2_KERNEL_HEADERS_AS_KERNEL case, the exclusion is actually not needed. Indeed, KERNEL_HEADERS_SOURCE is computed to be the same value as LINUX_SOURCE, and linux.mk already adds LINUX_SOURCE to BR_NO_CHECK_HASH_FOR. For the other cases, we should exclude the BR2_KERNEL_HEADERS_VERSION case because there the user supplies the version so it can't be included in the .hash file.

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
