This patch makes it possible to format the rootfs using btrfs. It
introduces the option; BR2_TARGET_ROOTFS_BTRFS.
When selected, the user is able to specify the filesystem size, label,
options, and node and sector sizes. The new files are based on
fs/ext2/{Config.in,ext2.mk}

[Thomas:
- fix issues pointed by Yann (duplicated empty line, missing quotes
around default values for string options)
- use -f option so that we don't have to remove the image file before
creating it again
- use the --byte-count option to set the filesystem size, which
avoids the need for doing a "truncate -s"
- remove the possible explanation of a mkfs.btrfs error. Indeed,
mkfs.btrfs automatically extends the size of the image as needed,
so the size passed can never be "too small".
- fix check-package warnings in Config.in 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
