samsung S7562

This device is not supported by LineageOS but the kernel is apparently in GitHub.

What works

• Compilation of kernel, system and initramfs
• pmOS starts up if a pre-compiled kernel (from the original boot.img) is used, along with the newly built initramfs and system image. Telnet, decrypt filesystem, and ssh (partially) works

What does not work

• pmOS does not boot with the newly built kernel. it only works if a pre-built factory kernel is used
• ssh fails with a 'cannot create channel 0' error, which can be bypassed with ssh user@<ip> '/bin/sh'. With this, no prompt is shown (i.e. no "$" or "%"), but commands can be typed and executed and the results are displayed
• No graphics are displayed on the screen, weston fails with Failed to open frame buffer device ‘/dev/fb0’: No such file or directory
