Some code cleanup for GCC 4.x

2006-03-11T21:53:33+00:00

Cleanup (get rid of debug code that sneaked in)

2006-03-06T23:22:36+00:00

Merge with /home/wd/git/u-boot/master

Code cleanup.

Cleanup of NAND support of delta board using the Monahans Data Flash

2006-03-06T14:04:25+00:00

Controller.

NAND finally working. Two bugs fixed:

2006-03-06T12:45:42+00:00

 * 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.

Minor code cleanup

2006-03-06T12:03:37+00:00

Merge the new NAND code (testing-NAND brach); see doc/README.nand

2006-03-06T10:25:22+00:00

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]

Re-factoring the legacy NAND code (legacy NAND now only in board-specific

2006-03-05T17:57:33+00:00

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.

Fix problem with flash_get_size() from CFI driver update

2006-03-01T16:00:49+00:00

Patch by Stefan Roese, 1 Mar 2006

Major CFI-FLASH driver update:

2006-02-28T14:29:58+00:00

* 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".

  Patch by Stefan Roese, 28 Feb 2006

* Update drivers/cfi_flash.c:
  - find_sector() called in both versions of flash_write_cfiword()
  Patch by Peter Pearse, 27th Feb 2006

* 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
