Grzegorz Bernacki 7f725bcd5c Import work done under project/nand (@235533) into head.
The NAND Flash environment consists of several distinct components:
  - NAND framework (drivers harness for NAND controllers and NAND chips)
  - NAND simulator (NANDsim)
  - NAND file system (NAND FS)
  - Companion tools and utilities
  - Documentation (manual pages)

This work is still experimental. Please use with caution.
