The kernel is based on Samsung's downstream kernel for the device. Some
configuration changes are required to make the kernel to work:
* Tizen kernel uses SLP USB gadget, changed to Android USB gadget.
* sprdfb patches and modification on the devicetree files are required
  to use the framebuffer.
* Other required pmOS kernel settings were enabled.
* Tizen does not use initramfs, use RAMDISK partition to store initramfs
  of pmOS (like heimdall-isorec configuration). As far as I know, no
  alternative OS exists for this device so this is the very first usage.
* Flash the root file system to USER, as ROOTFS is < 1 GB in size and
  USER is about 2.7 GB.

* Changed kernel configuration for firmware path to follow postmarketOS.
* Post install script to mount CSA partition

CSA partition [1] contains non-volatile data for Tizen devices. As
Samsung Z1 uses this partition to store Wi-Fi and Bluetooth information,
mount this partition to use within postmarketOS.

This synchronizes behavior with other heimdall-isorec devices.
