The BR2_ARCH definition is like this: * i486 for the i486 platform * i586 for a small number of platforms * i686 for all other x86 platforms when used in 32-bit, but we enumerate their entire list * x86_64 for all x86 64-bit platforms The list for i686 is long and needs to be extended everytime a new platform is added, with no added value. So this commit simplifies that by replacing this long list with just: default "i686" if BR2_i386 This works because Kconfig guarantees us that if an i386 platform matches an earlier case (i486 or one of the i586 platforms), the i486 and i586 earlier in the list will match.

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.
