M50fw016 is not erased on T56. Records some garbage.
When working with M50FW016, several errors were revealed:
1. Erase only the first 0x10000 bytes
2. Writes only to these 0x10000 bytes and reads garbage.
3. Over 0x10000 bytes does not erase, reads garbage.
On T48 erasing, writing, reading passes without errors.
Fix please.
