Hilledkinged e8bc1251a7 Initial Evolinx beryllium bootimage creator 
// About this first creator
* Features automated bootimage creation for ebbg and tianma panels
* Creates custom ramdisk with its own init system to boot over into sdcard rootfs
* Includes some firmware blobs for ramdisk ( such as gpu, wlan and etc taht gets loaded initially )

// TODO
* Create automated rootfs flasher that can be used with twrp
