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.
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
