samsung-kiran: new device (Samsung Z1) (MR 3234) 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. samsung-kiran: Update device and firmware packages * 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. [1] https://docs.tizen.org/platform/porting/kernel/ linux-samsung-kiran: Use lzop to decompress initramfs This synchronizes behavior with other heimdall-isorec devices. [ci:skip-build] Already built successfuly on CI in MR

Subject: [PATCH 4/4] samsung-kiran: Fix sprdfb to get a working screen
* Specify sprdfb memory address so mmap() won't fail
* Apply commit 6632662e89687748f20a023eb443c53d77fc270a from Tizen
(profile/mobile/platform/kernel/linux-3.10-sc7730) to fix broken
ioctl()
