d4a58af380 drivers/mtd/mtd/mtd_procfs/c and include/nuttx/mtd/mtd.h: Add an interface to un-regiser an MTD procfs entry.
drivers/mtd/filemtd.c:  New new MTD conversion layer that will convert a regular file (or driver file) to an MTD device.  This is useful for testing on the simulation using the hostfs.

7b590ec9a2 drivers/mtd/smart.c Fixed SmartFS wear level error that occurs when the logical sector size is too small to save all wear level status bytes in a single sector. Logical sectors 1 and 2 were simply not being allocated and then the read_sector and write_sector routines were failing. From Ken Petit 2015-11-18 18:12:06 -06:00

af9590eef7 Extend the AT24Cxx MTD driver with support for -04,-08 and -16 parts.
These parts utilize the same one-byte-address in the I2C protocol as the -02,
but requires different I2C addresses for different banks of the EEPROM.

c9661ad5a7 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions.
