Hello

I have some prototype product, router with MT7620. On board it is also 64MB serial flash memory instaled SPI. U-Boot handling this memory also. In this moment I thinking about how to instaled OpenWRT. Whether arch MIPS is supported in OpenWRT with 64MB ? A looked on Device Tree, and I only saw driver m25p80 which supporting probably max 32MB. So what if I whant  more memory ?Which driver Can I use ? Is it possible at all ?
