Added three patches to fix the mmc issue as described here: https://github.com/SolidHal/Librean/issues/17 Source for the patches is the chrome os kernel. Links to the commits can be found in the issue. Locking into version 4.17.2 for the time being. Better organized patches. Added logic to only apply tested patches on fresh kernel. Moved some debian build improvements in from my devsus master branch, including switching from xfce to lxqt. May be able to add option between the two in the future, as the issue that led to switching DEs may have been with the xorg video drivers that are now skipped by the script and not xfce itself. Cleaned up uneeded old configs |

Librean
A build system for making blobless debian and mainline kernel for the Asus c201 Chromebook
Build a mainline kernel and Debian filesystem with: No blobs, anywhere. Support for Aetheros AR271 usb wifi dongles through the open source firmware Minimal toolset intended as a based, including tools to setup a wifi connection Sources from only main, not contrib or non-free which keeps Debian libre TODO: basic graphical desktop like xfce
why
Combined with libreboot,an AR271 wifi dongle, and a libre OS (like Debian, the one built by this) the asus c201 is a fully libre machine with no blobs, or microcode.
Dependencies
Librean has been tested on Debian 9 Stretch (in a vm) These packages are required:
apt install --no-install-recommends --no-install-suggests \
parted cgpt \
git gawk device-tree-compiler vboot-kernel-utils gcc-arm-none-eabi \
u-boot-tools \
gcc make libc-dev wget g++ cmake \
binfmt-support qemu-user-static debootstrap \
lzip libssl-dev libncurses-dev flex bison
Build
Currently split between 'buildKernel.sh' and 'buildDebianFs.sh' Run the kernel one then the fs one.
Install
Write the 2GB image to a flash drive, which contains the full 15GB (acutally 14.7GB) to write to the internal storage. We can do this since the 15GB image is a sparse file.
sudo dd if=debian-stretch-c201-libre-2GB.img of=/dev/$USB_DEVICE bs=50M
Now on the C201, login as root. The password is blank. Write the 15GB image to the internal storage For me this was /dev/mmcblk2 but it may be /dev/mmcblk1 for you depending on what device it assigns to sdcards
dd if=/debian-stretch-c201-libre-2GB.img of=/dev/$DEVICE bs=50M
Reboot. Run /Install.sh which will install xfce, wicd, and some device configurations. This will reboot one last time when done.
/Install.sh
You should now be greeted by the xfce login screen.
If you just want a basic enviroment without xfce upu can skip running Install.sh but I recommend installing wicd-curses for wifi configuration.
GPU Support

Build the wifi dongle into the laptop

Troubleshooting
The pulse audio mixer will only run if you are logged in as a non root account. This is an issue (feature?) of pulse audio
