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. Obtained from: Semihalf Supported by: FreeBSD Foundation, Juniper Networks
