If this flashis CFI conform, just use the existing CFI driver. Search for CFG_FLASH_CFI* in the existing board config files to get an idea.

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 Data (start 0xfffb4000, len 0x4000) saved at 0xfac1b8 Erasing Flash... FFFB0000 ... FFFB7FFF ...Erase Flash from 0xfffb0000 to 0xfffb7fff in Bank # 1 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

This is wrong. Th CFI flash driver also supports bottom and top boot sector types.
