CFI supports only the same size sector flash, but
AT49BV320C organized like
8 * 4K
63 * 32K
similar flash driver i saw in the
board/at91rm9200dk/flash.c file. I took that file and
tried to modify the commands, but i am getting the
following Error...

=> saveenv
Saving Environment to Flash...
Protect off FFFB8000 ... FFFBFFFF
Un-Protecting sectors 62..62 in bank 1
Un-Protected 1 sectors
Protect off FFFB0000 ... FFFB7FFF
Un-Protecting sectors 61..61 in bank 1
Un-Protected 1 sectors
Data to save 0x4000

Erasing Flash... FFFB0000 ... FFFB7FFF ...Erase Flash

Erasing sector 61 ... ok.
Erased 1 sectors
Writing to Flash...  FFFB0005 ... FFFB4000 ...
unaligned destination not supported
Start and/or end address not on sector boundary

is't the right procedure what i am trying to add the
flash support for AT49BV320C
