Dear Ramesh,

this issue could be connected to a patch i recently posted to the 
list, where the erase command is now allowed to be customizable for 
CFI AMD compatible chips only.

Are you using board_flash_get_legacy in your board files ?

If yes, could you just add after line 1834 in cfi_flash.c

                        info->cmd_reset = AMD_CMD_RESET;
+                       info->cmd_erase_sector = AMD_CMD_ERASE_SECTOR;

And report back if erasing now works ?

Many Thanks,
Angelo Dureghello
