flash problem in u-boot

Hi,all

I use the Am29LV160DT flash in my cyclone custom board.

and the flash used in the altera' dev board is Am29LV065D , and the size of sectors are the same , but this is not the case in Am29LV160DT , the organisation of sectors is as follow:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and

thirty-one 64 Kbyte sectors (byte mode)

— One 8 Kword, two 4 Kword, one 16 Kword, and

thirty-one 32 Kword sectors (word mode)[/b]

--- Quote End ---

how to modify the source code to make it work?

has anyone meet this question before? how to solve it?

Any replies are highly appreciated .
