Description

Currently, is_flat_memory could return 3 different values:

  • True when the module is flat memory
  • False when the module is not flat memory
  • None when the EEPROM read returns None or empty bytearray

When it returns None, we should not assume that the module is NOT a flat memory. Instead, it would be safer to treat it as a flat memory.

Motivation and Context

This PR is to make is_flat_memory only returns two state, True or False. And if EEPROM reading returns None or empty bytearray, we should treat the module as a flat memory.

How Has This Been Tested?

Manual test
