[U-Boot] Asymmetric Flash JS28F256P33B95

Hi all,

I'd like to use the flash JS28F256P33B95, are there problems with the uboot? The flash is asymmetric: 255 sectors of 128kb and the last sector splitted in 4*32kb. What is the best uboot configuration to use that? Do I have to set CFG_MAX_FLASH_SECT to 255 or 256? I'd like to use the bottom of the flash to deploy the environment but how can I set the uboot to perform that?

Thanks.

Regards,

Marco
