M25P16

Hi,
For my secondary project I chose M25P16 as external memory (it was the only SPI flash IC, from the list of the compatible memories, which I found from the biggest distributors in Europe).
But I noticed that sector size is 64KB, from the usual 4KB. So, SUOTA probably will not work out of the box.
What modifications must be done? From my understanding I should make production header address and firmware offsets to match sector boundary in:
1. SUOTA app source.
2. Secondary bootloader.
3.图像生成器脚本。

Do I miss something?
