ADSP-21573 4 byte addressing for flashing

Question

We are trying to change the flash chip from 128Mbits to 256Mbits for this we have to change from 3byte addressing mode to 4 byte addressing mode in the flash driver. 
 We are using ADSP21573 processor and W25Q256JV flash chip. 
 Please let us know whether there are any changes required in SPI side of ADSP21573, in order to make this compatible to 4 byte addressing mode.

Hi, 
 For using 4byte addressing mode in 256 Mbits flash chip, SPI does not need any changes. As you are already aware, flash driver file needs to be changed as per the required configuration. Hope this helps.
