[MT6255 SPASION ADUMUX] Tool shows download fail at 65% progress.
Because tool costs a lot of time to wait SPASION flash program and erase, PC side and Target side hand-share mechanism is insufficient that PC side timeout and report the download fail.

[SV3 NAND project] Check resource version instead of project ID between MAUI ROM and MBA resource ROM, if MAUI ROM contain resource version.

[MT6252, MT6251] Support WIN-BOND OTP function
1) There are four security register banks(OTP) in WINBOND flash. The bank0 is Reserved by Win-bond for future use. We only use bank1~bank3. One banks size is 0x100. User could directly use 0x0 to 0x300 address that the flash tool driver will direct these address from bank1 to bank3
2) The WIN-BOND flash unique feature is the security register banks are not One-Time-Program. That could be erase by specific command. In order to prevent format these regions, user must use "Lock" these regions in order to prevent data changed in security banks.

Bug fixes:
[MT6276] Fix the bug about Create CBR fail caused from bad block management method

[SV3 Platform] MMAA support 4 flash ID comparison.
