svn commit: r260121 - head/sys/dev/nand

New Revision: 260121
URL: http://svnweb.freebsd.org/changeset/base/260121

Log:
  Add support for Samsung K9F2G08U0A (256MiB SLC) NAND found on some old
  Atmel boards I have.
  
  # All Samsung, Toshiba and SanDisk parts will need to be in this table
  # since they don't conform to the ONFI specification (they are all Toggle
  # parts). There's some standards for the additional bytes so there's some hope
  # to decode them automatically on a per-vendor basis, but even that has
  # problems (and is what motivated the ONFI parameter page).
