Automatically initialize the AT24 SPI EEPROM driver when NSH starts.

The Serial EEPROM was mounted on an external adaptor board and
|
|
connected to the LaunchPad thusly:
|
|
|
|
- VCC -- VCC
|
|
- GND -- GND
|
|
- PB2 -- SCL
|

- PB3 -- SDA

---help---
|
|
Create the MTD driver for the AT24 and "wrap" the AT24 as a standard
|
|
block driver that could then, for example, be mounted using FAT or
|
|
any other file system. Any file system may be used, but there will
|
|
be no wear-leveling.

|
|
---help---
|
|
Create the MTD driver for the AT24 and mount the AT24 device as
|
|
a wear-leveling, NuttX FLASH file system (NXFFS). The downside of
|
|
NXFFS is that it can be very slow.
