* 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.

* 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

- 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.
