Some basic "generic" secure devices support optimized

Known issues/warnings/info :
1. [NAND on MT6570] v1712,v1736 loader packages NOT SHOULD BE USED! Since they have ftl/ecc errors!
In result you will give read/write FW errors and rest problems at all.
Recommend use v1724 for FACTORY FW flashing, v18xx line for Infinity FW Flash Read and Write
2. [NAND on MT6570] In some cases "stuck on logo" devices can be fixed only via FFU (whole flash) format!
3. [MEMORY TOOL] Partitions state on MEMORY TOOL will be empty in MT6570 NAND phones, it is normal and cannot be fixed.
Read-Write data, which you want, ignore "EMPTY" states.
4. ADL checksum MAY NOT WORK CORRECT on MT6570 NAND devices! Result - stuck after system/userdata partition flashing
5. FileSystem flashing on some SBC-enabled devices ( except SYSTEM/CACHE/USER ) may fail! Solution - exclude them from flashing list.
6. Cheap MT6739 devices require BATTERY REMOVING after EVERY operation in most cases!
7. Meizu support is limited by Preloader Level ( No BROM SLA ) - you must UNTICK "PMT Update" and "PRELOADER" partition from flashing list!

Main
- New look and design. All simplified and optimized much, as possible. [ please refer to v2 interface introduction ]
- New core. All code made from scratch.
- New boot chain selection mode - automatic ( via defined user combination ) or manual.
- New connection
- Complete error handling and explanation
- Internal EMIDB cover 99% of existing memory devices on both - NAND and eMMC devices
- Easy end user customization for adding support for new device etc

Flasher
- Completely new flasher design, which allow customize whole flashing process [ please refer to v2 interface introduction ]

FW Reader
- Completely new core, which allow handle all existing types and flash devices.

Service
- Security repair NOT require reboot to meta, not required CDC drivers or whatever else. All direct.
- Format FS include different mode, optimized for different secure devices type ( with FORMAT, WRITE protection )
- During NVRAM read/write SW also verify it condition and data

MEMORY TOOL activated!
Easy, fast and ultimate solution now come in MTK too!
- Support eMMC and NAND flash IC`secure
- Allow READ, WRITE, ERASE partitions
- Show partitions states and info only for eMMC devices
- Allow RE-init PMT ( from scatter )

Other
Lot of other changes from v1 line, which not mandatory to mention

1. [NAND on MT6570] UBI SPARSE image flashing may take MUCH time (up to 5 minutes and more) for some devices!
3. [MEMORY TOOL] Partitions state on MEMORY TOOL will be empty in MT6570 NAND phones, it is normal and cannot be fixed.
Read-write data, which you want, ignore "EMPTY" states.
4. [MEMORY TOOL] Old protocol secure devices (MT6750/MT6755) - LeEco and similar
In some cases WIPE partition may not work!
5. ADL checksum MAY NOT WORK CORRECT on MT6570 NAND/eMMC devices! Result - stuck after system/userdata partition flashing
6. FileSyhstems flashing on some SBC-enabled devices ( except SYSTEM/CACHE/USER ) may fail! Solution - exclude them from flashing list.
7. Device with NV_TYPE2 security may not work yet for repair sec!
