depends on NSH_ARCHINIT && TIVA_I2C0 && MTD_AT24XX
---help---
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

config TM4C123G_LAUNCHPAD_AT24_FTL
bool "Create AT24 block driver"
---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.
config TM4C123G_LAUNCHPAD_AT24_NXFFS
bool "Create AT24 NXFFS file system"
depends on FS_NXFFS
---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.
