(This is Work in Progress!)

Code cleanup.

Controller.

 * For READ_STATUS and READID commands always 8 bytes need to be read from
   NDDB. Otherwise they stay there and get send to flash as the first data
   word when writing.

 * In nand_base.c the oob variable is not reset so this->oob_buf is
   overwritten what eventually screws up the bad block descriptor table.

Rewrite of NAND code based on what is in 2.6.12 Linux kernel
Patch by Ladislav Michl, 29 Jun 2005

[Merge with /home/tur/nand/u-boot]

code and in SoC code). Boards using the old way have CFG_NAND_LEGACY and
BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
implemented for these boards.

 * Debug message can be turned on and off.
 * Waiting for events now times out.
 * Implemented RESET command.
 * Added appropriate nand_bbt_descriptor and nand_oobinfo.

Remaining Problems:
 * Read Status still behaves weird an returns invalid stuff sometimes.
 * ECC Placement does not respect our scheme in nand_oobinfo.

don't ask me why. There are still bugs in the bad block logic.

after all.

start at an offset of 4 bytes from the start of the page.

delta_cmdfunc function, because this bit is only set once after a command
is sent and this allows read functions to be called multiple times.

use hush shell.

Patch by Stefan Roese, 28 Feb 2006

* Add env-variable "unlock" to handle initial state of sectors
  (locked/unlocked).

  Only the U-Boot image and it's environment is protected,
  all other sectors are unprotected (unlocked) if flash
  hardware protection is used (CFG_FLASH_PROTECTION) and
  the environment variable "unlock" is set to "yes".

* Update drivers/cfi_flash.c:
  - find_sector() called in both versions of flash_write_cfiword()

* CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode
  Patch by Jose Maria Lopez, 16 Jan 2006

* Add support for AMD/Spansion Flashes in flash_write_cfibuffer
  Patch by Alex Bastos and Thomas Schaefer, 2005-08-29

* Changes/fixes for drivers/cfi_flash.c:
  We *should* check if there are any error bits if the previous call
  returned ERR_OK (Otherwise we will have output an error message in
  flash_status_check() already.)  The original code would only check for
  error bits if flash_status_check() returns ERR_TIMEOUT.
  Patch by Marcus Hall, 23 Aug 2005

* Changes/fixes for drivers/cfi_flash.c:
  - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c
  - Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c
  Patch by Sangmoon Kim, 19 Aug 2005

* Fixes for drivers/cfi_flash.c:
  - Fix wrong timeout value usage in flash_status_check()
  - Round write_tout up when converting to msec in flash_get_size()
  - Remove clearing flash status at the end of flash_write_cfibuffer()
    which sets Intel 28F640J3 flash back to command mode on CSB472

This is a first version of the testing-NAND branch merged back to main.
