79b4cda076 Major CFI-FLASH driver update:
* 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.

* 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

d96f41e016 Add support for TQM8541/8555 boards, TQM85xx support reworked:
- Support for TQM8541/8555 boards added.
- Complete rework of TQM8540/8560 support.
- Common TQM85xx code now supports all current TQM85xx platforms
  (TQM8540/8541/8555/8560).
- DDR SDRAM size detection added.
- CAS latency default values can be overwritten by setting "serial#"
  to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
  If problems are detected with this non default CAS latency,
  the defualt values will be used instead.
- FLASH size detection added.
- Moved FCC ethernet driver initialization behind TSEC driver init
  -> TSEC is first device.
