The generic extension set 'G' is realy a base with the minimal set of extensions needed to be comfortable (but not required) to run a linux-bassed system. Similarly, we consider the custom to be about the custom set of features (not about a custom core implementing such a set). As such, we allow that a core with the G set can have futher extensions without requiring it to be configured as a custom set. We drop the intermediate symbols with the prompts, and move the prompts to the previously hidden symbols, and add a prompt for the I set. This alows one to clearly see what the generic set is about, without having to delve into the help and hunt the list of selected symbol. Note however that the G set implies Zicsr and Zifencei, but we have no prompt for thos two, because in Buildroot, we assume that they are mandatory and always present, like the I set (which they previously were part of).

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.
