Flash sector size
Hi All,
I have just found if is possible to write to device tree any information about flash sector size.
Just for clearing we use dts/dtb for run-time qemu(cpu emulator) configuration and I would like to configure flash and sectors size based on any information from DTS.
Is it any proposed solution?
Thanks,
Michal

Sorry for the really late reply. I'm just cleaning up my mail backlog now.
Yes, there is a binding for describing flash in the device tree. See Documentation/powerpc/dts-bindings/mtd-physmap.txt for some details. NOR is well supported. NAND drivers use it, but each NAND driver may require additional properties depending on the NAND controller device driver. Flash size can be specified, but I don't think there is a binding yet for sector size since in most cases the sector size is probed from the device itself.
