How to apply driverless device into harmony v3

Question

I would like to apply HM628128 and MX25L800 to File System of MPLAB® Harmony v3. But, the file system (MEMORY driver) of harmony v3 with default condition can be only applicatable to RAM/ROM listed below.

1. AT24
2. AT25
3. AT25DF
4. SST26
5. NVM
6. RAM

Does anyone know the way such as code new driver and recode MEMEORY driver to solve this problem? Thank you in advance.
