-Build a Buildroot rootfs
-------------------------
-
-Buildroot rootfs aims to be the most lightweight rootfs for experimental use. `make buildroot_rootfs` runs the defconfig target for rootfs-only build and then builds the rootfs tarball and a CPIO archive for initramfs. `make image/sd_buildroot.img` makes a bootable SD image in `image` directory like the typical Brainux SD image.
-
-If you want to customize the build of Buildroot, `cd` into `buildroot` and use the following targets:
-
- - `make menuconfig` to change the configuration
- - `make` to build the rootfs (`-j` option might give you extra speed)
-
-`image/sd_buildroot.img` target expects presence of the tarball at `buildroot/output/images/rootfs.tar`. You'll have to `clean` and rebuild every time you change the Buildroot's config before making the SD image.
-

 Known issues

-If you use GCC 10 for the host compiler, `make ubuild` may fail.
+If you using gcc 10 for host compiler, `make ubuild` may fail.  
 To complete build, open `/u-boot-brain/scripts/dtc/dtc-lexer.lex.c` or `/u-boot-brain/scripts/dtc/dtc-parser.tab.c` then comment out `YYLTYPE yylloc;`
